Well in the beginning there was just the one electro-strong-weak-gravity field... until inflation cooled everything down enough for the four “fundamental” forces to freeze out. Edit: ok so really there is only theoretical evidence of an ele

A handy rule of... thumb I like to keep in mind is that it takes about 1 ns for light to travel from your hand to your eye... (... and then 10,000,000 ns for your brain to process it...)

If you were further in the black hole’s gravity well than the photons in the photon sphere, you would see them redshift and eventually freeze, right? I.e. from inside the photons don’t appear to escape

Is it ok to mentally replace the word/concept “gravitational field” with “energy density field”? If so it resolves the mysterious central relationship this field has for all the others.

“Electromagnetic waves” are the manifestation of relative motion between an electric charge and an observer’s reference frame. A detector inside a cryogenic ion trap would detect much lower energy EM radiation from the contained cloud of io

That’s a good question! I wouldn’t be surprised if the academic team in this case developed something relatively simple. Let’s try to find out how they dispatched the synthesis orders they made over the two years. Was it excel or csv at the

It is creating an electric field for every observer not in a reference frame at rest with respect to the electron.

NASA's DSCOVR satellite is positioned such that it is always between the earth and the sun, so it always has a view of the sunny side of the earth. I think its' EPIC product produces a full-disk image every hour. https:/&#x2

There's also the ISS HDEV livestream from the space station. The stream is only up when the ISS is on the Earth's daylight side, so ~45 min of its ~90 min orbit. https://eol.jsc.nasa.gov/ESRS/HDEV/

How are you thinking of making the wallpaper live? Poll the server every 15 minutes for a new image, and if there is one, use @mczachurski's script to regenerate the background image .heic file?

Hi! I just came across the author's repo was thinking the same thing! https://github.com/mczachurski/wallpapper I think the best source would be GOES-R / GOES-17 full disc geocolor images. I'll post back

One approach would be to record 100-to-1000 trials of how human drivers navigate each particular edge case in vehicles instrumented for autonomous driving. Sadly, no one seems to have figured out a way to economically motivate human drivers

The reason I brought this up was to wonder how insane (just a little? or totally impossible?!) it would be if 100% of public transportation was serviced by "TNCs" in the city. > "On an average weekday, more than 5,700 TNC

Ok, fair enough - for urban centers. Although to your first point, lets go farther and say that 50% of core city streets could be closed to traffic and repurposed for walking/biking pedestrians. --- So... this got really long. It was j

Does anyone have back-of-the-napkin estimates of total passenger throughput for central public transportation vs ride share transportation for any metropolitan area? If public transit i.e. Muni serves 10x or 100x riders each day vs ride sha

Freight traffic dominates the utilization of the rail network in the US and is prioritized over other traffic. Freight trains travel slowly. This is why US passenger train service is so poor compared to Europe. > The picture for freight
