Not sure if the wording is right but didn't want to make a walltext title, the point is: making a parabolic mirror is still consumption, but once you have it that's a literal 0 emissions from heat. How long (let's say hours of gently simmering) would it take to balance the emissions for building it, compared to not building but still using a regular induction plate or gas stove?

(yeah, I know the energy mix makes a difference for induction, choose what you want)

He sustained a fractured skull, a fractured T11 vertebra (spine), a fractured sternum (chest), a concussion, and a burst eardrum- as per google.
How fast was he traveling at impact? And how hard of an impact would that have been?

For context, this was found under an Instagram video of a nuclear engineer reacting to a low poly shorts video. Curious to see what the math looks like for this proposed situation!

I googled that, but the difference seems too much to believe. Google says an acre of solar panels will produce 250-500 MWh/year while an acre of corn produces about 12.3 MWh/year.

So an acre of solar panels replaces 20-40 acres of ethanol corn? That seems too good to be true. And TBH, I trust the Google AI about as far as I can throw it.

Can anyone shed some light on the truth of these numbers

Saw this and now am genuinely wondering how fast you'd need to drive.

There is probably a bunch of digitial archives or something for universities or researchers, like Encyclopedias or Britannica's. But my first thought was "how about downloading the entirety of wikipedias database?"
So i suppose thats my secondary question too.

I'm sorry if this isn't the right place to ask, I think this sub fits best, but I also didn't see the same request in the subs history.

Thank you.

I was playing ark last night and tamed a Maewing, it was the first Maewing I've tamed and it seemed absurdly fast, crossing the ocean of Fjordur in a couple seconds, so I was curious as to how fast a Maewing actually is and how crazy the G-forces would be turning on one, I'm not knowledgeable enough to even estimate the first question. (Edit) According to this post, https://www.reddit.com/r/ARK/s/iQLwbEncOQ it's top speed is 248 miles per hour.

I was in a discussion with a co-worker about the lottery. He plays once a week and has for a number of years. I mentioned that I didn't. He said he always plays the same numbers every week, not because they're lucky, but because he believes that playing the same numbers every week somehow increases his odds of winning. I couldn't get any sort of rational explanation for this and I tried to explain to him that because every lottery drawing is from all the possible numbers available in the drawing, he has the same possibility of winning regardless of the numbers that he plays. Only if he bought more than one ticket with different sets of numbers, in any one drawing, did he actually increase his chance of winning. He refused to believe that I was right and he was wrong. Neither of us really has the math to justify our opinions. Can someone help prove me right?

if I was sailing my boat from East to West in the ocean and during the sunset, at which speed I should sail to maintain a perpetual sunset in front of me ?
