Two brothers, talking science and telling bad jokes. Barely scripted, sometimes accurate, almost funny, Thursdays at 8PM pacific.
Ep 297: FTL, and the relativistic refrigerator
FTL, and the relativistic refrigerator
In honor of April fools’ day, we start with real science and then go off into wild speculation. We talk about the possibility of faster than light, and time travel. Not to be taken seriously, but fun!
Here’s a video that covers some relativity basics, like time dilation and length contraction.
Here’s a site that explores relativity, by using an imaginary ship that travels close to the speed of light.
Here’s a video that explains Bell’s inequality, and what that has to do with physics.
Bell's Theorem: The Quantum Venn Diagram Paradox
Here’s a talk on testing bell’s inequality without loopholes.
Significant loophole-free test of Bell’s theorem with entangled photons
Here’s a site about quantum entanglement between the earth and orbit.
Physicists link quantum memories across the longest distance ever
Here’s something about cosmic rays, muons, and relativity.
How To Prove Einstein's Relativity In The Palm Of Your Hand
And here, you can get a book published in 1917, that includes thought experiments on how communication faster than light might act.

Ep 296: Apollo’s fiery chariot
Apollo’s fiery chariot
To go to the moon, you need the right equipment. This includes the giant Saturn V rocket, and the escape system to get you away from your giant rocket when something goes wrong. Join us for a look at the hardware of the Apollo program.
Here’s some info about the Little Joe II.

Here’s an accidental but successful test of the Apollo launch escape system.

Ep 295: Humans, IN SPACE!
Humans, IN SPACE!
We talk about the people of the Mercury and Gemini programs. Over and over again, the astronauts saved the mission went things went wrong. They also played a few silly jokes on one another, and we go along for the ride.
Here is a link to NASA’s site on the Gemini program.
Gemini - Bridge to the Moon
Here’s a video by NASA about the Gemini missions.

Ep 294: Animals, IN SPACE!
Animals, IN SPACE!
Before humans went into space, animals were sent. We talk about some animal and human astronauts, a little about rockets and a side trip to using nuclear explosions for thrust.
Here’s a site on the history of animals in space.

Here’s a ted talk by the son of one of the people who thought blowing up atom bombs behind the ship would be a good way to make it move.
George Dyson: The story of Project Orion
Here’s some footage of a test craft. It’s a model for project Orion, using conventional explosives

Here’s a link to info on the Little Joe rocket, which was made by bundling together Sergeant missiles
And here’s a vintage video about Sergeant missiles, which were bundled together to make the Little Joe rockets
Ep293: Arms race to space race
Arms race to space race
At the end of world war II, nuclear weapons had been used for war. By 1949, the USSR had successfully tested their own atom bomb. Everyone scrambled to build rockets that could launch their terror weapons at any part of the globe, especially at each other. The same rockets being built for war were used to reach into space.
Here are a few videos on specific impulse, with much clearer explanations than ours.

Ep 292: Supersonic flight, rocket planes and the edge of space
Supersonic flight, rocket planes and the edge of space
After world war II, the world became very interested in super sonic flight, and high altitude research. Along with a side trip to how jet engines work, we take a look at rocket planes—the first manned vehicles to reach the edge of space.
As a side note, have a link to a short article about the MIT icon drive powered plane.
MIT engineers fly first-ever plane with no moving parts
Here’s more information about the pulse jet engine.
