Bruships 119: Cool Books - but they're definitely a Mixture
Study Bruships 119: Cool Books - but they're definitely a Mixture, a Dr. Alex Clarke video from 30 Jul 2023, with 117 time notes. Topics include Aircraft Carriers, Battlecruisers, Live Q&A.
Time notes
- 2:51QuestionWhy were frigates and ships of the line rare on the west coast of the Americas?AnswerQ&A
The voyage was long and expensive, while local threats rarely justified sending a battle-fleet unit instead of a frigate or smaller ship.
- 4:17QuestionWas the Royal Navy naive to expect its battlecruisers to stay outside the battle line?AnswerQ&A
The argument here is that Britain's battleships already supplied numerical superiority, leaving the battlecruisers free for fast manoeuvre and flank protection. Their effective use still depended on command and communications.
- 8:42Airborne early warning and Falklands fighter directionNotable Point
The Falklands War illustrates why fighters alone cannot provide a complete maritime air-defence system without early warning.
- 12:09QuestionCould the desire to use all available numbers explain placing battlecruisers in the battle line?AnswerQ&A
Yes, but concentrating numbers did not make battlecruisers suitable for every role, and armour comparisons must account for each navy's requirements.
- 14:54Why air-defence planning must allow for a capable opponentNotable Point
Confidence in fighter superiority still needs to account for the surveillance and force requirements of fighting a peer.
- 19:37Jutland: better shells and gunnery disciplineNotable Point
Better shell quality and more attention to accurate gunnery are proposed as ways to change the losses at Jutland.
- 23:54Jutland: a strategic victory and a tactical drawNotable Point
Separating Beatty's and Jellicoe's actions explains the assessment of Jutland as a tactical draw despite Britain's heavier ship losses.
- 25:06Why armour coverage matters alongside maximum thicknessNotable Point
Comparing the area protected explains why maximum belt thickness alone gives an incomplete picture of a capital ship's armour.
- 26:55QuestionWould Britain have built more Renown-class battlecruisers as a quick response to the Mackensen class?AnswerQ&A
Probably only if the Mackensens appeared likely to enter service; a modified third Renown could bridge the gap before the Admiral class.
- 30:55QuestionWhat could have made the Type 82 destroyer more economically viable than the Type 42 alternative?AnswerQ&A
A simpler power plant might have helped, but the principal issue was willingness to fund a large, capable ship.
- 33:03QuestionWhat is your favourite English-language naming convention for World War II ship classes?AnswerQ&A
The example chosen is the Royal Navy's escort names: flowers, rivers, bays, and lochs supplied enough distinct names for mass wartime construction.
- 33:57QuestionWould the cordite rotation introduced after the loss of Vanguard have helped if it had been in place before Jutland?AnswerQ&A
It might have helped, but following magazine and flash-protection procedures mattered much more than propellant chemistry alone.
- 35:06The dreadnought race was wider than Britain and GermanyNotable Point
British gun choices and the example of USS Texas place dreadnought development within a global shipbuilding contest.
- 38:04QuestionWho might have led the Imperial German Navy better than Alfred von Tirpitz?AnswerQ&A
Henning von Holtzendorff is the preferred alternative.
- 39:40QuestionCould more stable cordite have given crews more time to react between a turret hit and the resulting conflagration?AnswerQ&A
Very little, once fire had entered an open ammunition-handling route.
- 40:17QuestionWhy did the Imperial German Navy move from 11-inch to 12-inch guns instead of jumping to 12.5-inch or 13-inch weapons?AnswerQ&A
Limited investment and manufacturing infrastructure constrained the calibre increase, despite Germany having the necessary engineering knowledge.
- 42:26How triple-turret Königs could have changed British battleship plansNotable Point
A counterfactual König battery leads to a larger, faster Queen Elizabeth design as a possible British response.
- 46:13QuestionDid the British 12-inch and 13.5-inch capital ships actually have flash protections for passing charges?AnswerQ&A
Yes. All had protections, although the arrangements and levels of protection differed.
- 49:51QuestionWas Midway an anomaly or a product of the technology of its time?AnswerQ&A
A mixture, with both technology and contemporary design choices contributing.
- 50:09QuestionWas Russia holding back its military capabilities in Ukraine, or did logistical problems limit what it could do?AnswerQ&A
The assessment is that logistical failures were themselves a capability limit, rather than evidence that Russia was deliberately withholding most of its strength.
- 51:23QuestionWhy were NATO countries not doing more to support Ukraine, in this July 2023 assessment?AnswerQ&A
The explanation offered is that earlier underpreparation for peer conflict left them trying to restore readiness while supplying Ukraine from existing weapons stocks.
- 52:01QuestionHow long would Australia remain after the Washington Naval Treaty if 20,000-ton, 12-inch cruisers were allowed?AnswerQ&A
She would probably serve until one of the new cruisers was ready to replace her.
- 52:43QuestionWhat might happen if Russia divided into two states after the Russian Revolution?AnswerQ&A
Japan would probably have a strong chance of taking Siberian territory because the region lacked the manpower and industry to resist alone.
- 53:18QuestionWhat alternative Renown-class battlecruiser designs were considered, and how would they have differed?AnswerQ&A
There were few developed alternatives because available equipment drove a rapid design decision. A four-twin-turret option is recalled tentatively, and a third ship would probably have differed as a second batch.
- 54:08QuestionHow might a much more decisive British victory at Jutland have affected later naval treaties and the war?AnswerQ&A
It could have enabled Baltic operations and sharper pressure on German supply, potentially changing the war before treaty questions arose.
- 58:15QuestionDid sea mines suffer the same detonation problems as the torpedoes used by different countries?AnswerQ&A
Generally less so: mines used older arrangements or a stable position, while moving torpedoes made influence detonation more complicated.
- 59:30QuestionHow do modern carrier aircraft sink ships when torpedo bombers are no longer their usual anti-ship weapon?AnswerQ&A
Missiles can disable sensors, command facilities, or propulsion, or breach and damage the hull enough to cause flooding.
- 1:00:20QuestionIf Britain called its first-generation battlecruisers heavy armoured cruisers, would the Washington treaty still treat them as capital ships?AnswerQ&A
That would depend on how much negotiating effort and political capital Britain was prepared to spend.
- 1:00:37QuestionAre propeller shafts hollow, and what advantage does that provide?AnswerQ&A
Some are hollow to reduce weight and, with controllable-pitch propellers, to accommodate the control mechanism.
- 1:03:38QuestionWhich aircraft carriers did the Royal Navy have in 1939?AnswerQ&A
The list recalled from memory is Ark Royal, Courageous, Glorious, Furious, Eagle, Hermes, and Argus, with uncertainty over Argus's administrative status. Further carriers were launched, building, or on order.
- 1:04:45QuestionWere Satsuma and South Carolina laid down before HMS Dreadnought?AnswerQ&A
Satsuma was laid down earlier, but carried a mixed main battery. The South Carolina class was laid down in December 1906, after Dreadnought's October 1905 start.
- 1:07:43Respectful disagreement in historical debateNotable Point
Respectful replies to historical objections let other readers compare the arguments and reach their own conclusions.
- 1:09:01QuestionCould bombardment off Belgium accompany Baltic operations after a decisive British victory at Jutland?AnswerQ&A
Yes, in the counterfactual assessment. Fleet size, quick refits, and the availability of older ships could support both tasks without requiring the 13.5-inch capital ships for coastal bombardment.
- 1:09:58Testing a historical argument against its strongest objectionsNotable Point
A practical historical method builds the case against a conclusion before deciding how confidently to defend it.
- 1:12:23QuestionDo we know the true maximum speeds of Royal Navy capital ships and cruisers?AnswerQ&A
No precise universal figure is offered: official, design, and emergency speeds can differ when machinery is driven beyond its normal limits.
- 1:14:25QuestionWhat panic could a submarine-borne commando raid have caused in Japan alongside the Doolittle raid?AnswerQ&A
A successful attack on important targets could prompt earlier troop withdrawals from Manchuria and the cancellation of some operations in China.
- 1:18:38QuestionIs there a good book about a naval situation where weather was a greater threat than enemy action?AnswerQ&A
No specific book is named, but the Arctic convoys, Falklands War, and Typhoon Cobra are offered as examples.
- 1:21:54Duke of York and the Home Fleet's manpower crisisChapter
Personnel shortages and neglected equipment left Duke of York immobilised before a 1948 refit restored more of her capability.
- 1:24:16Duke of York's final western Atlantic cruise and a disputed crew transferNotable Point
A long Atlantic deployment ended with a manpower proposal that would have denied 145 sailors their Christmas leave.
- 1:25:21Exercise Sunrise exposes carrier limits in bad weatherNotable Point
A 1948 convoy exercise forced the cancellation of a carrier strike when most embarked aircraft could barely fly.
- 1:26:34Atomic-bomb dispersal competes with anti-submarine protectionNotable Point
Exercise Sunrise tested how widely major ships could disperse against atomic attack while preserving an effective submarine screen.
- 1:27:32Anson and Howe train the fleet under fuel and manpower restrictionsNotable Point
Postwar battleships supported exercises and refuelled destroyers even while crews, ammunition, and fuel were tightly constrained.
- 1:29:35Exercise Verity brings Western Union navies togetherNotable Point
Anson joined a 1949 multinational exercise that linked postwar battleship service with Western Union defence cooperation.
- 1:35:29QuestionHow would an Italian carrier entering service in 1941 change the Mediterranean war?AnswerQ&A
It could lead to a major carrier battle, but an Adriatic construction yard would probably be needed to protect it from British attack before completion.
- 1:37:13QuestionHow would a world without nuclear weapons change military development and doctrine?AnswerQ&A
The effects on Japan must be considered first, followed by the loss of nuclear deterrence in the Cold War and the continuing limits of Soviet logistics.
- 1:38:34QuestionWhat was a major British missed opportunity during the naval-treaty era?AnswerQ&A
An improved common 15-inch gun for Nelson, Rodney, and older capital ships could have made fleet-wide upgrades easier.
- 1:39:45Two Lexington battlecruisers could guard fast carrier groupsNotable Point
The proposed advantage of completing Lexington battlecruisers was a fast gun escort capable of protecting carriers from cruisers.
- 1:40:31How propulsion technology separated battlecruisers from fast battleshipsNotable Point
Mission and machinery weight explain the transition from cruiser-killing battlecruisers to fast battleships able to fight the battle line.
- 1:41:22QuestionWhat if the Washington treaty treated cruiser-hunting battlecruisers as a separate category from battleships?AnswerQ&A
Hood or the Renown class could supply the benchmark, with consequences for American Lexingtons, but no definite tonnage limit is proposed.
- 1:42:00QuestionHow would Britain respond if Germany concentrated large-warship construction on a Scharnhorst pattern, including carriers?AnswerQ&A
Britain would probably build carriers and capital ships faster, while continued German use of 11-inch guns would give little reason to change the KGV's 14-inch armament.
- 1:43:09QuestionWhat might an American battlecruiser built in the 1930s have looked like?AnswerQ&A
A roughly thirty-six-knot ship intended to operate with fast carrier groups.
- 1:44:18QuestionWhat would a Franco-Italian naval war in the early 1940s look like without outside help?AnswerQ&A
Italy might win, but the exact timing and the hypothetical arrival of the Joffre carriers could change the balance.
- 1:44:57QuestionWhat World War II mistakes came from applying lessons learned in World War I?AnswerQ&A
One suggested land-war example is the BEF's preference for digging in and planning a counterattack instead of launching an attack.
- 1:46:00QuestionWhat if the Royal Navy had developed marine gas turbines in the early or mid-1920s?AnswerQ&A
Destroyers would probably benefit first, while refitting Warspite or Renown could provide much more power for the machinery weight and space.
- 1:48:51QuestionCould a twin-engine F-35 retain vertical-takeoff-and-landing capability?AnswerQ&A
Probably, but balancing the engines would be very complicated, and the assessment remains tentative.
- 1:54:03Submarine escape training as a test of pressure and nerveChapter
A reading from Richard Humphreys's Under Pressure describes the physical and psychological demands of free-ascent training.
- 1:59:24QuestionWhat if Japan had successfully relieved Attu and defeated the American invasion force?AnswerQ&A
The United States would probably return with a force two or three times as large.
- 2:01:49QuestionWould earlier Alaska-class cruisers have been better than two Lexingtons completed as battlecruisers, including at Guadalcanal?AnswerQ&A
Their value would depend on construction timing, training, and fitted technology; Lexington battlecruisers would share machinery and facilities with two converted carrier sisters.
- 2:08:13QuestionWould receiving the Douglas SBD Dauntless earlier have greatly improved the Royal Navy's air arm?AnswerQ&A
A faster aircraft would still need to suit British missions and equipment; inconsistent aircraft terminology leaves the specific Douglas comparison uncertain.
- 2:12:33QuestionWas the Royal Navy's long-term plan for eight Centaurs to replace the ten Colossus and six Majestic light fleet carriers?AnswerQ&A
Possibly, but the intended long-term force centred on Audacious and Malta fleet carriers; reliance on light fleet carriers followed the circumstances at the war's end.
- 2:13:15QuestionWhy keep destroyers and light cruisers in a large UAD battle when they are fragile and 12-inch guns can defeat enemy small ships?AnswerQ&A
Effective destroyers and torpedoes can still contribute to the action despite the ships' vulnerability to heavy gunfire.
- 2:13:42QuestionIf the Royal Navy had gas turbines in the 1920s, how soon would Hood receive them?AnswerQ&A
Probably during a 1930s reconstruction, after Nelson and Rodney had been designed with them; the machinery savings could encourage faster modernisation.
- 2:16:22QuestionCould the Japanese surface fleet have reached the Americans within gun range after receiving their reported position?AnswerQ&A
Probably not from its position, although an immediate turn on receiving the report might have made interception possible.
- 2:16:51QuestionWhy did the TBD Devastator become obsolete so soon after entering service?AnswerQ&A
Aircraft generations moved quickly, and the Devastator was overtaken during a normal three- to four-year replacement cycle.
- 2:17:22QuestionDid fleet destroyers use high- and low-pressure turbine arrangements like capital ships?AnswerQ&A
Most did.
- 2:18:25QuestionWhich battleships were the tallest ever built?AnswerQ&A
Yamato and Musashi are the tentative choices, based on a mental estimate whose result depends on how height is calculated.
- 2:20:38QuestionWhat is a good source on how the Fleet Air Arm learned to operate Corsairs from carriers?AnswerQ&A
Eric 'Winkle' Brown's naval-aircraft writing and Wings on My Sleeve are recommended because he carried out the testing work.
- 2:25:28Preparing the British Pacific Fleet's Sakishima strikesChapter
Fleet rotation, refuelling, radar positioning and rescue cover supported the British Pacific Fleet's effort to keep Japanese airfields unusable.
- 2:28:07Miyako bombardment: gunfire, spotting and the return to the carriersChapter
The 4 May bombardment of Miyako shows how battleships and cruisers coordinated airburst fire, spotting and ammunition expenditure before carrier attacks forced an early return.
- 2:32:51QuestionCould Nelson and Rodney have been the experimental ships for an early combined marine-gas-turbine installation?AnswerQ&A
Cruisers would probably have tested it first, possibly through a County-class experimental ship or a specially built batch.
- 2:34:54QuestionWhy did the Royal Navy enter the Second World War with apparently second-rate carrier aircraft?AnswerQ&A
Older aircraft, delayed replacements and procurement compromises require separate explanations; the Roc is singled out as a conceptual dead end.
- 2:39:11QuestionWhat if the surrendered High Seas Fleet had been divided among the Allies instead of scuttled?AnswerQ&A
Allied fleets would have scrambled to absorb the ships, making both the naval balance and a Washington-style treaty much harder to settle.
- 2:40:28QuestionHow might the war change if a Barracuda-type British torpedo bomber entered service in 1939?AnswerQ&A
It could improve survivability and strike performance, including during the Channel Dash and the 1942 Indian Ocean raid, if it met British torpedo requirements and received continued development.
- 2:42:46QuestionWhen did the Royal Navy face its greatest danger during the Revolutionary and Napoleonic Wars?AnswerQ&A
The mutinies were an acute internal danger, while the threat to Baltic naval stores made the Copenhagen crisis strategically frightening.
- 2:44:43How Barracuda delays produced the Albacore stopgapNotable Point
Repeated engine changes delayed the Fairey Barracuda and forced the Fleet Air Arm to field the Albacore as an interim torpedo bomber.
- 2:46:12Churchill's naval advocacy under European-war prioritiesNotable Point
A criticism of Churchill's Admiralty leadership distinguishes enthusiasm for naval affairs from listening to advice and defending naval requirements.
- 2:47:19QuestionWhat is an example of overwhelming naval firepower being used against limited opposition?AnswerQ&A
The short war at Zanzibar is offered as an example of Britain deploying overwhelming naval force and then imposing tougher terms after the fighting.
- 2:48:26QuestionWas the Barracuda's difficult flying reputation justified?AnswerQ&A
It was less pleasant to fly than the Swordfish, and its development had suffered from repeated engine changes.
- 2:49:23The fictional Sea Lance and the real Barracuda programmeNotable Point
The invented Sea Lance prompts a comparison with Britain's actual Barracuda programme and the Air Ministry decisions that disrupted it.
- 2:54:45QuestionWhich older Royal Navy carriers would Audacious- and Malta-class ships have replaced after the war?AnswerQ&A
They would continue the planned retirement of the pre-war carriers, leaving the modern fleet-carrier classes to form the core force.
- 2:57:57Why territorial states and merchant centres used naval forceChapter
Territorial states and merchant centres had different motives for using sea power, including state revenue, trade protection and commercially organised convoys.
- 2:59:17London's commercial institutions and British sea powerNotable Point
London's trained bands, merchant companies and interest in convoy protection help explain Britain as a hybrid commercial and territorial sea power.
- 3:01:38The commercial centres that supplied ships and convoy protectionChapter
Named European shipping centres show how merchant capital supplied large vessels, convoy organisations and ships that could be converted for war.
- 3:03:27QuestionWould an expanded Canadian battlecruiser force lead to demands for battleships?AnswerQ&A
Probably not; further battlecruisers, potentially at Tiger's level rather than the Indefatigable type, are considered more likely.
- 3:03:54QuestionHow do rail ferries align their tracks precisely when they dock?AnswerQ&A
Guide systems, mooring lines, and sometimes chains hold the ferry in exact alignment, with skilled crews making the final adjustment.
- 3:04:52QuestionWhat would a Pacific war look like if Japan attacked the United States in 1939 or 1940?AnswerQ&A
Japan would fight before the Kido Butai matured, while early American and British entry would create a very different alliance structure and wider war.
- 3:06:31QuestionHow would a much larger post-war British carrier fleet be deployed?AnswerQ&A
Its deployment would depend on the opponent and mission; deterrence favours regional presence, while war favours concentration.
- 3:10:03QuestionWould Britain have considered the Curtiss Helldiver if it had been less flawed initially?AnswerQ&A
Britain considered it anyway; a better version might have been adopted, although the actual proposal did not work out.
- 3:10:29QuestionDid anyone identify the problems of lacking a full-sized carrier when the Falklands conflict began?AnswerQ&A
Michael Clapp is recalled as having written a lengthy warning about the problems, although the passage's precise form and timing are not established here.
- 3:11:06QuestionWhy did the Kido Butai use six carriers at Pearl Harbor rather than every available Japanese carrier?AnswerQ&A
Many other carriers lacked readiness, aircraft, pilots, or tanker support, while the six-carrier force already stretched available resources.
- 3:11:38William's invasion fleet and the English failure to interceptChapter
Richard Harding's account follows the intelligence failures, command decisions and winds that let William land at Torbay without a fleet battle.
- 3:15:39Why the English fleet remained inactive in 1688Chapter
Competing explanations for English naval inaction distinguish professional caution, divided loyalties and possible political opportunism.
- 3:18:07How 1688 changed English expectations of invasionChapter
The apparent ease of William's landing helped make invasion defence a central English naval concern while France threatened trade and possessions.
- 3:19:23QuestionWhich navy is most likely to acquire an aircraft carrier for the first time?AnswerQ&A
South Korea is the candidate suggested in July 2023, based on the value of a mobile airfield and concerns about regional carrier development.
- 3:21:46Japan's helicopter destroyers as a path back to carriersNotable Point
The Izumo-class F-35B conversion is placed within a progression from helicopter destroyers toward purpose-built Japanese carriers.
- 3:25:44QuestionGiven a quoted Bismarck-class cost of $490 million in 1940 US dollars, could Germany have built something much cheaper?AnswerQ&A
The quoted cost is itself disputed: incomplete records and omitted infrastructure spending could put the total higher. No cheaper alternative is priced.
- 3:27:58QuestionDid Sweden and the Dutch Republic simply accept the loss of great-power status?AnswerQ&A
No. Sweden adjusted slowly, and the Dutch continued to pursue influence through other means.
- 3:33:21QuestionCould a V/STOL aircraft operate from an ordinary frigate's helicopter deck?AnswerQ&A
Emergency use may be possible, but routine operations need a larger deck, and an F-35B also needs reinforcement and heat protection.
- 3:34:13QuestionWhy do navies appear to overlook the value of large, flexible platforms?AnswerQ&A
They value them, but peacetime budgets fund serial tasks while war demands many tasks in parallel, requiring more hulls.
- 3:35:40QuestionHow did the ranges of British, American, and Japanese carrier aircraft fit their navies' doctrines?AnswerQ&A
The comparison links American and Japanese aircraft to concentrated strikes and British aircraft to repeated, often nocturnal attacks. Useful radius, survivability and support for troops ashore all shape the design.
- 3:39:15Admiral Rodney between prize money and strategic dutyChapter
A reading from Peter Hore's The Habit of Victory tests Admiral Rodney's claim that he sacrificed personal profit to protect the empire.
- 3:49:15QuestionWould scrapping some wartime ships pay for keeping the others in reserve for the next twenty years?AnswerQ&A
No, scrap receipts are not considered sufficient for that arrangement.
- 3:49:37QuestionHow did the American Independence class compare with the British Colossus, Majestic, and Centaur light carriers?AnswerQ&A
The American ships supplemented the Essex surge, while Britain depended more heavily on light fleet carriers as its larger carrier programme recovered.
- 3:51:14QuestionIs there a book comparing the advantages and disadvantages of large and small aircraft carriers?AnswerQ&A
No specific book is recommended. The explanation instead emphasises more efficient use of fixed ship spaces, a longer flight deck, and enough spare aircraft to sustain patrols and strikes.
- 3:53:45How an 18-aircraft pool sustains four fighters on patrolNotable Point
The four-aircraft patrol example shows why aircraft in maintenance, on alert and in reserve count toward carrier air-group size.
- 3:56:19What good-faith historical research requiresNotable Point
Good historical work makes its evidence traceable and engages with material that could challenge its conclusions.
- 3:59:07How inaccessible sources complicate historical disagreementNotable Point
A disagreement over Japanese and British sources distinguishes a documented research limitation from proof that a conclusion is correct.
- 4:03:26Treaty language and actual political relationshipsNotable Point
The Franco-Ottoman alliance and agreements involving China illustrate why diplomatic formulas require historical context.
- 4:05:13QuestionWhich design rejected during the N3/G3 process could have been a logical successor?AnswerQ&A
K3 is suggested. The detailed case for it is left to the separate N3/G3 design discussion.
- 4:05:41QuestionWhat is the assessment of Sumida's naval-history books?AnswerQ&A
They are judged good overall, with less agreement about Arthur Pollen and no confidently identified book singled out.
- 4:09:31QuestionShould the Against All Odds Boulton Paul Sea Lance be imagined as a larger Barracuda-type aircraft with a radial engine?AnswerQ&A
Yes, that broadly fits the fictional description. The separate recollection of a real Boulton Paul Barracuda competitor remains uncertain.
- 4:09:53QuestionWere any escorts designed with only Hedgehog or Squid and light anti-aircraft weapons, without a deck gun?AnswerQ&A
No; escorts still needed a gun for surfaced submarines and encounters with torpedo boats such as German Schnellboote.
- 4:10:41QuestionWhich capital ships have been overlooked in naval history?AnswerQ&A
The Littorio, Dunkerque, and Gangut classes are suggested as deserving more English-language attention.
- 4:12:20QuestionWhat naval forces could help Ukraine protect grain shipping?AnswerQ&A
The hypothetical package combines submarines, anti-submarine escorts, Sea Ceptor and land-based air cover. Its training and staffing demands make receiving and operating the whole force unlikely in the assessment given here.
- 4:13:48Type 26 and Constellation approach versatility differentlyNotable Point
The 2023 comparison contrasts an ASW design broadened for other roles with a general-purpose design adapted for ASW.
- 4:16:09QuestionCould a surfaced U-boat historically defeat an escort in a gun duel?AnswerQ&A
A lucky victory is considered theoretically possible, but no historical example is identified. Damage preventing the submarine from diving would leave it exposed to further escorts.
- 4:17:47QuestionHow can a researcher recognise a fruitless project before going deeply into it?AnswerQ&A
There is no sure way to know in advance; the investigation has to show whether the idea bears fruit.
