My mom was playing Jeopardy on her Alexa and one of the questions was about a state in Mexico. Her boyfriend, who was very drunk, adamantly insists that it’s a trick question because “Mexico doesn’t have states.” It’s literally called the United Mexican States. Two of my aunts are from Mexico. It took like two hours to get him off the subject.

Confidently ignorant people really bother me. Even if I thought that I would’ve thought “Is that true?” and spent a second googling it. It is amazing how some folks are devoid of even the slightest curiosity but are blindly overconfident.

i got into an argument with my in law about a 60$ sticker to block the ‘waves’ on my phone. for my health. and my phone will still work… it was a hologram sticker.

I’ve got the new ones that also block radiation, they’re on sale for 120$

well, they do sell ones that work. you can measure them blocking all em radiation from exiting out the back of your phone… instead blasting all of it into your head. significantly more of it too, since the normal reaction of a phone that loses signal is to boost its own in order to find a tower.

But blocking any of it is useless because none of it is going into your head, the wavelength of the radio waves is too large to penetrate skin or bone, it bounces off harmlessly like am/fm radio waves. It’s in the nonionizing range of the em spectrum, unlike ionizing em waves like X-rays, gamma rays, radon emissions, etc that do penetrate human bodies and can cause protein or DNA damage.

actually no, some of it gets absorbed. that’s why there are SAR values available for all cellphones. it measures how many watts of heat get absorbed per kilogram of brain.

since it’s non-ionizing though, the only effect is a slight heating. like microwatts of heating. 15 minutes in direct sunlight is equal to millions of phone calls. but we do measure it!

the one where the democrats are the ‘party of slavery’ because of what the parties stood for in 1860. yeah that’s why I’m voting for Lincoln and the union this year dumbfucks

And yet California—a solidly blue state—just voted by public referendum to uphold slavery. https://en.wikipedia.org/wiki/2024_California_Proposition_6

Yeah, the problem here is calling them the party of slavery, when both parties are blatantly in favor of it.

They might want to look up how the parties flipped during the civil rights era.

I wonder why so many Democrats left the party during the civil rights movement? I wonder why David Duke left the Democrat party? I guess we’ll never know.

Toss up : a coworker who I would have counted as quite intelligent said we haven’t been to the moon because “it’s impossible to launch a rocket to the moon and land on it because rockets go in a straight line. Trying to time the shot of the rocket, and get to the moon at the exact moment when the moon gets to the right spot would be astronomically impossible. The odds of pulling that off at the speed you would be traveling and the distance you travel… Well the odds are effectively zero.”

"Also you can’t catch up to the moon because the moon is traveling faster then our rockets can go "

Either that or a prochoice individual who voted for Trump…

How does this person think things like ICBMs work? They just go straight up and away from the earth and can’t turn?

When he used both arguments in the same conversation. I shrugged and stopped talking. Nothing to gain by continuing the conversation

No, you must go back and tell him that the moon moves at a very predictable rate and once you get close enough it will even pull you in.

Also I’m pretty sure the ISS moves a lot faster than the moon but we still manage to dock spacecraft with it. I’m pretty sure it’s a bit smaller than the moon and docking can require higher precision than landing on a surface. Even Boeing managed to do it.

How does this person think guided missiles work? “Well the plane moved so we missed.”

"Also you can’t catch up to the moon because the moon is traveling faster then our rockets can go "

  1. Not true so discussion over right there
  2. Even if its angular velocity was faster than a rocket its radial velocity is nearly 0 so all you would have to do to intercept it is to lead it. No different than shooting a moving target at long ranges.

Okay im curious. What about shooting something into the sun is very hard?

The earth has a lot of angular momentum, in fact the planets combined have more than the sun and planet formation may actually be necessary to “bleed off” angular momentum from protostellar discs for star formation, but I digress. So if you were to aim directly at the sun you’d miss it wildly as the tangential motion of the earth would be added to your motion. Even worse it would miss the sun, go around it, and orbit back to where you came from. A bad thing if you were trying to toss, say, radioactive waste into the sun. To hit the sun you have to bleed off all of that angular momentum by using rockets (very expensive) or do what NASA usually does and use gravity assists swinging by planets to gain or lose energy. The Parker solar probe had to do a bunch of swings past Venus to lose enough angular momentum to get close to the sun.

The first argument is more or less understandable (still wrong): you can’t just propel yourself upwards at your earliest convenience to reach the moon, you have to play around with orbital mechanics.
If your friend’s idea of a moon-worthy vessel is an unsteerable rocket with infinite fuel and a chair strapped to it… well the odds are effectively zero.

The second argument? bro, last time I checked the moon was still orbiting Earth

The friend should play Kerbal Space Program. It will be a fun way to show that yes, it’s really hard, but it is possible to play around with orbital mechanics and get to the moon.

And then it will show that an unsteerable rocket with infinite fuel and a chair strapped to it is also possible, just really really hard.

I imagine the latter isn’t too hard, you just have to get it right just before leaving the atmosphere (quick saves help); however, isn’t landing (not crashing nor rolling around) on the Mün without steering straight up impossible?

Though I can see some rocket landing on a planet with an atmosphere…
