Engineers are terrible at picking product names. Some of the company/product names (picked by marketing folks) I disliked the most at first turned out to be the most "brandable" and successful.

I thought it was strongly discouraged to have sensationalist titles on scholarly papers? Maybe that's just in physics.

I love that the box and form factor are retro 80's but the keyboard is fully modern. Very good design decisions.

In roulette this is known as the "dealers signature" where a bored zoned out dealer can sometimes hit the same region/sector of the wheel on consecutive spins. I've seen this happen (or at least appear to happen) in real

It's pretty amazing that we all carry around a device in our pocket with more wireless Internet bandwidth than anyone had (in any media) in 1994.

Another place to look is DSD/mbelib, although to exploit you would have to transmit on a frequency they were monitoring and any replies/confirmation would have to come from another path (Internet). Since a common use case for that

A simple non-mathematical resolution is that no information has been gained by selecting the first envelope. Since no information about the contents was available before selecting the first envelope switching envelopes is a neutral act. Whi

Beach towns tend to have a main road one or two blocks from the ocean that may run for many miles and connect several beach towns. That can easily become a focal point for rolling "car shows". In North/South Carolina beaches

Fun fact: “proper” polynomials have only non-negative integer exponents but you can construct other non-linear polynomial-like equations with negative and even rational exponents. They work the same with the number of real roots related to

One reason even well designed camera systems struggle to reproduce accurate colors is the relatively wide bandpass filters for each color. This is especially true for modern digital sensors with green, cyan, and clear Bayer filters. While i

Some perspective that may help: If the Sun were replaced by black hole with the same mass as the Sun at the center of the Solar System we wouldn't automatically get sucked into it. A very cold Earth would continue to orbit the black ho

We can't even measure the gravitational constant to more than about 4.5 significant digits. Most other natural constants are in the 7-12 digit range and improving along with our technology. Measurement of big G hasn't convincingly

For Interferometry to work the data from different baselines has to be collected at the same time so waiting 6 months does not help. Spacecraft could theoretically be used to extend the baselines but the volume of data to be transferred is

It's actually one of the sharpest images ever made - in terms of angular resolution. The Sag.A* ring is about 51 microarcseconds in diameter. The EHT has a theoretical resolution of ~25 micro arcseconds. For comparison NirCam on Webb

One of the findings they announced at the press conference is that the spin of the black hole is not aligned with the galactic plane but is tilted "towards us" so that it is viewed face on. How unexpected is that?

Additional dimensions also give you new ways to define angles. 2D: axis-axis (a-a) 3D: a-a, plane-axis (p-a) 4D: a-a, p-a, plane-plane (p-p), volume-axis (v-a) etc.
