Science Doesn't Understand How Ice Forms
What starts off as a simple desire to get a macro shot of a droplet of water freezing quickly leads George to the very edge of scientific knowledge and a shocking fact about most of the water on Earth.
*Note: in the droplets I’m freezing, all the dendrites would have likely come from a *single* nucleation point, not multiple ones.

Did the Chemical Building Blocks of Life Form in Space?
Переглядів 6 тис.2 місяці тому
For years scientists thought complex molecules could only be formed on Earth. But what if we did find these kinds of molecules out in space? What if they could be formed not just in and around biology but also in cold, dark corners of the universe? Scientists have wondered if they might have been early seeds for life on earth, or even a stockpile of molecular building blocks deposited onto our ...
Does Toyota Know Something That We Don’t?

The 2044 Toyota Prius might just be powered by… ammonia. Ammonia is combustible, and holds promise as a relatively low-effort way to decarbonize the internal combustion engine - but the devil’s in the details. Join George as he discovers at least one detail by burning stuff in his basement. *Note:* the model piston we used in this video shows air and fuel entering the cylinder together. This de...

    Yeah the fact that it's in literally everything is kinda an issue. Thanks war on drugs. In a move reminiscent of the prohibition and the addition of poison to alcohol not meant for consumption,(which killed tens of thousands of people) acetaminophen being in literally everything is both a move to punish people who may abuse meds and kill them too. The downside being it's actually difficult to combine meds for those that actually need to do so. One of the many things one of my family members complains about as a doc.

    Hydrogen power is the future of vehicle power. EV doesnt have the battery technology the military is willing to release to the public. Amonia is being over used already and is more expensive than hydrogen. Toyota is developing the MODERNIZED hydrogen powered car right now. Though the technology has existed for about 100 years. Bet money all the largest oil producers are all looking at hydrogen production in their near future.

      "Freeze distilling" tops out a bit lower, around 94%, and that's only if you have the equipment to very slowly bring the temp down to around -120° C.
