Tesla announced that it reached a new milestone with its Supercharger network: it now has over 30,000 fast-chargers around the world.
Earlier this summer, we reported on how Tesla is gearing up for a giant Supercharger expansion ahead of opening the network to other EVs.
Following Tesla’s confirmation of this, the automaker started hiring many new charging design managers in charge of opening new stations in the US.
When the researchers bathed this engineered silk in sunlight, they found that it stayed 3.5°C cooler than the surrounding air because of its ability to reflect most sunlight and radiate heat. It is the first fabric to be developed that stays colder than the surrounding air when in sunlight.
The researchers also found that when they draped the engineered silk over a surface designed to simulate skin, it kept the skin 8°C cooler under direct sunlight than natural silk did – and it kept the skin 12.5°C cooler than cotton did. The simulated skin was made of silicone rubber that was wrapped around a heater to mimic body warmth.
In the final part of their experiments, they made a collared long-sleeved shirt from the engineered silk and asked a volunteer to wear it while standing out in the sun on a 37°C day. Infrared images revealed that the shirt stayed cool. Similar infrared images captured of the volunteer wearing shirts made of natural silk or cotton showed that these fabrics warmed up. “Wearing the engineered silk on a hot day under sunlight, one feels much cooler than wearing normal textiles such as cotton,” says Zhu.

A good definition of information in physics: “information contained in a physical system = the number of yes/no questions you need to get answered to fully specify the system.”

Summary:
In quantum mechanics, it’s just as natural to go forward in time as going backwards. And if you look at a typical Feynman diagram, you can turn the diagram either way. Where does this transition from time symmetry at the quantum level, to time asymmetry at the macro level occur?
To understand its irreversibility, we have to look for other irreversible processes in nature to see if there is any correlation — such as in thermodynamics, Entropy.
If you traveled 10,000 years into the future, what would planet Earth look like? Would most of its surface be covered in volcanoes? Or would it be frozen in ice? What if you traveled even further, to one million years in the future? Would all of the oceans have evaporated? Or would it have become one giant water world? Now, what about one billion years? Would there be any humans left? Or would they have settled in other parts of the galaxy?
