  • The Discovery That Transformed Pi


    For thousands of years, mathematicians were calculating Pi the obvious but numerically inefficient way. Then Newton came along and changed the game. This video is sponsored by Brilliant. The first 314 people to sign up via get 20% off a yearly subscription.

  • The Drydock - Episode 136


    00:00:00 - Intro

    00:00:39 - Why did guns on protected cruisers often have no protection?

    00:05:01 - Why did the New York class battleships use triple expansion engines when the Floridas and Wyomings had already switched to turbines?

    00:10:09 - Which nation of the Free Navies had the best names for their warships?

    00:14:16 - Why is the Union Flag flying in many of the pics of Russian warships?

    00:16:22 - Did the en echelon turrets of ALL dreadnoughts(that had them) caused damage to the all of the ships?

    00:19:14 - In regards to cross-deck fire, were there technical difficulties in designing ships with many centerline turrets, or was it a matter of doctrine?

    00:25:35 - What year, outside of during a major war, did the British spend the most as a percent of GDP on the Royal Navy?

    00:27:24 - Suppose the Austrian Fleet had sortied in early 1915 (before Italy joined the war) to try and disrupt the Anglo-French operations at the Dardanelles. Could they have achieved anything, or would it just have been a suicide charge?

    00:30:21 - Why do cruisers exist?

    00:34:17 - Did the 50 US destroyers sent to Britain in the ships for bases deal materially contribute to Britain's fight against the U-boats?

    00:36:49 - How would you rate Hipper and Scheer's effectivness as commanders at Jutland?

    00:43:12 - Considering how close to the coast the major battles of the Western Front in WW1 often were (Passchendaele, Ypres, Ostende etc) was their ever use of naval bombardment to break through the German lines in the north?

    00:46:44 - Which civilians would you say have contributed the most to naval technology and development?

    00:50:06 - Was there more nuance to the Roman naval strategy to defeat the Carthaginians, other than hybrid naval-land warfare?

    00:52:49 - What was the RN submarine with two twin turrets?

    00:57:13 - What part did navies take in the Boxer Uprising?

    01:00:45 - Was there any realistic chance in the 19th and 20th centuries of China developing a sufficiently powerful naval force to deter invasions?

  • How do you test lunar lander technology on Earth before going to the Moon?


    NASA uses commercial flight providers like Masten Space Systems vertical takeoff vertical landing rocket, Xodiac, to validate it during a recent flight in Mojave, California

    The flight test simulates some of the maneuvers of a lunar lander. Designed for precision landing in a very tightly defined area, the Navigation Doppler Lidar technology transmits laser beams to the ground that bounce back to a sensor, providing information about the lander's velocity and distance to the ground. Unlike Earth where GPS satellites are used to navigate, NASA needs new technology to explore the Moon and other planets so a precision landing technology could open possibilities to land anywhere even near a crater
