There are two components - horizontal and vertical. For a bullet fired straight up, horizontal component is negligible, as the bullet will spend enough time in flight for it to decrease due to air resistance. The vertical component is prima

Vaccine efficacy is measured against symptomatic COVID‑19. It's quite possible that asymptomatic carriers transmit more (e.g., because they do not self isolate, or because they shed the virus for a longer period of time). You may be ri

I don't think any vaccine study had odds of transmission as one of the end points. How do you even design such a study?

The look-up table can also be generated on the device itself using CORDIC.

The linked article shows biological effects of low frequency electromagnetic fields, then argues that cell phone signals contain low frequency components "in the form of on/off pulsations, modulation, and signal variability".

High-frequency electromagnetic field aka ionizing radiation (X-ray, gamma) is well known to be genotoxic because it can break molecular bonds. The question is how non-ionizing radiation can affect molecular structure, if not by heating. I d

I'm not sure how modulation could have an effect, but there certainly were studies that used modulated signals: > The studies used 2G and 3G frequencies and modulations still used in voice calls and texting in the United States htt

Absence of evidence is not evidence of absence. That said, if we start with the premise that > Mobile phones emit radio frequency waves which, if absorbed by tissues, can cause heating and damage then there is no need to do a study. Know

Transmitting is not very different from receiving. In fact, there is reciprocity property.

The problem with this approach is that the correlations only work for average and below average cases. If someone is illiterate, chances are he's not going to be great at physics or medicine either. If someone is overweight, chances ar

This requires a precise internal clock that is always correct. If that clock drifts or is reset because the battery dies, GPS receiver would stop working.

GPS receiver does not know exact time. It has a built-in clock, but that clock is not very precise and is only used to speed up signal acquisition. The exact time is determined from the received signals. GPS receiver can determine its own p

Those look like flares, not shells. Still a fire hazard, but less destructive.

There are no definite or indefinite articles in either Russian or Ukranian, so they could not have been saying "the Ukraine". They used to say "in Ukraine" as "на Украине", which is now considered offensive. On

I think the allure here is the same as with ciphers. Everyone can create a cipher they cannot break, but cryptographers can break easily. Likewise, it's easy to invent another PRNG, but not so easy to figure out that, say, its output a

Is it any better than reduced-round versions of some ARX ciphers like ChaCha20?

It's actually not as stupid as it looks. There is a whole class of estimators [1] that use weighted average of quantiles. [1] https://en.wikipedia.org/wiki/L-estimator

It does not say how often it is updated. Wouldn't it be better to say "as of 8/29/2021, we have received no such requests and we are updating this page monthly".

That's not what the paper proposes, though. And doing that would invalidate a lot of chess tactics that rely on alternating moves.

If you can forget math, it means that you memorized it. I don't think one can ununderstand math. Oftentimes math is taught as a set of rules. Do these steps in order to get the answer. Works well to pass the test with minimum effort, d

You may not believe it, but parents outside the US do not do anything special when a child doesn't understand math. This seems to be uniquely American problem. Somehow in the US it's culturally acceptable and even normal to be bad
