I am the opposite of this. I've been through too may tornado events. Earthquakes may be bad and aftershocks are disturbing, but tornadoes make U-turns to go back for buildings they missed. Especially trailer parks.

I remember several years ago when the first tornado I heard about in California and it of course hit a trailer park outside of West Sacramento.

This one is for the geologists out there. This picture is a real picture that has been cartoonified for examples of glacial features. Unfortunately, I haven't been able to find the cartoon example.

I loved this dump, and yay Sacramento. I will say I've never heard about that particular tornado though.

#7 Smallpox, tetanus, measles, diphtheria, mumps, anthrax, etc. are all wonderfully natural. Ugly, bad vaccines and antibiotics are (mostly) manmade.

#12 No "Hail", and no "Fog". The issue isn't how much the weather changes from day to day. The issue is there only being 7 days of the week for which to display symbols.

#10 You have access to functionally unlimited resources, so you need to temper hedonism with things like diets. You don't want to be the rat that presses the cocaine button until it dies. That sad dog who's belly drags in the floor — you're the dog and you're the owner.

There's middle ground between one percent body fat and eating a whole cake whenever you want.

I mean honestly? I think that rat and dog enjoy/ed their life much more than I enjoy mine living in moderation.

#24 And what I find interesting - and certainly important today - is that the current population 7.95 billion people (which is almost certainly a low estimate, by the way) is up 100% from 50 years ago. The population has doubled in 50 years. I looked at what would happen if a disaster (plague, meteorite, whatever) wiped out 90% of humanity, and it would only set our numbers back about 200 years.

#5 Is the sun actually moving to make the sundial work? pretty sure it's the rotation and orbit of the Earth that makes it work, so there's only one moving part.

Right, the sun happens to be moving, but the sundial would still work even if it wasn't.

The soil texture one was abandoned by the British Soil Survey in the 70s, everybody used to dump everything in "loam"; so not useful.

#17 … Now I want Marvel or DC to introduce a new 'supervillain' whose backstory is that they invented new/cheaper methods of creating gemstones, but "Big Gemstone" bought out all the patents to block it, and ran smear campaigns calling them "fake" or "artificial". Their capers all involve robbing jewellers or museums, and then leaving the "stolen goods" in really obvious locations nearby… along with dozens of identical duplicates.

4 months ago | Likes 4 Dislikes 0

"Oh, you say that ONE of these is valuable, and the REST are all worthless? Good luck working out which is which, you fraudsters!" The cops just shrug, because "we got the goods back, right? It's more like unauthorised moving than theft". Batman enjoys the intellectual challenge, but never brings the perp in because he kinda agrees with them. Superman points out that he can ALSO make diamonds, by squeezing coal, and protects them. And Lex Luthor joins in to help (because it can make kryptonite)

Tumblr is not a good source of information although people still treat it like it is because someone sounds really confident about the stuff they write about even though there's never any articles etc backing them up

Came here to say this. Thank you. My degrees in plant bio were screaming...

As a biologist myself, I was ready to say the same thing. Not only that, but it’s incredibly basic scientific knowledge. Like, elementary school level almost.

For a moment I thought you were serious, and I was going to get angry because while the Magic School Bus HAS been to space, it did not do so using Rocketry!

That's not the Magic School Bus, though, that's some other school bus named "Vehicle Name" which, presumably, did use rockets.

#47 even worse: imagine eventually setting up a colony on the moon only to find out a non-negligible % of your colony is allergic to the stuff they'll be living on/in...

4 months ago | Likes 20 Dislikes 1

Well one of the biggest issues with setting up a Moon or Mars colony (after, of course, "we're going to have to ship a lot up there just to get started and that's really goddamn expensive") is dealing with all that dust (or "fines"). Not only is it bad for people, but it's bad for machines too. Apollo Program was a bit lucky in that regard as they were there for only a few days at a time, but for long term habitation it's something that needs to be dealt with, allergies or no.

4 months ago | Likes 2 Dislikes 0

If you had the resources to build a moon colony, you could bring a few hundred pounds of moon back to Earth and screen people before bringing them over.

4 months ago | Likes 3 Dislikes 0

This made my brain go on a weird little journey of 'what if moon dust turned out to be like drugs' and how fast there would be an industry of 'bring this shit back from the moon' and the inevitable sci-fi movie twist of 'hidden side effects may include...'

It makes sense, too, in a way. A body going "WHOA WHOA WHOA, what the FUCK is this? Literally never been exposed to this IN MY LIFE-"

I mean, histamine reactions can span a gamut here. either it basically shrugs it off (i.e. fights it subtle-like, so u barely notice), or it's ALL HANDS ON DECK, ALERT ALERT and yr system fucks itself up trying to fight to "threat".
Allergies are fun...

See my body likes to play a game called 'keep guessing, bitch!' where super common allergens are totally A-ok by it, but weird shit no one is allergic to is ALL HANDS ON DECK THIS IS NOT A DRILL! It's great fun.

#31 I suspect we could have returned to the Saturn V (half the capacity of Starshit but a proven design) at enormously lower cost than the Felon's projects.

except that the engines were all hand-made by welding artisans who are now either dead or in their 90s. And the blue prints/plans don't show all the very slight tweaks made to get them to work.

4 months ago | Likes 2 Dislikes 0

Quite true. My suspicion is that it would have taken a great deal less work and less money to bring back a proven design--one that was successful from the first launch---even with many, many tweaks, than to build a new unit from scratch. I might be wrong.

#8 or, you know, multiple or divide by .6 depending on which way you're going. Seems pretty simple.

4 months ago | Likes 31 Dislikes 1

Genuinely think it's easier to remember Fibonacci sequences than to try figuring dividing 87 by .6 in my head. If you have a phone with internet access you can just convert it any number of ways. I guess if you have a calculator but no phone your plan works.

4 months ago | Likes 5 Dislikes 1

I would have to start from 1 to figure out any Fibonacci number, so working with x0.5 or x2 and fudging the result is easier for me. If I need accurate numbers, to the internet I go.

4 months ago | Likes 3 Dislikes 0

People don't anymore because everyone has internet all the time, but back in my iPod Touch days I had a converter app that would let me change a bunch of stuff into whatever else.

And if you're really lazy and don't need that much accuracy, you can round that to 0.5 too. Obviously it introduces a modest amount of error but walking 2 km vs 1.67 km, the values are in the same ballpark. If something is a walkable distance, the added error won't change that, and if it's a distance you have time to drive to, the added error won't change that either.

In exchange the math is trivial to do in your head.

4 months ago | Likes 8 Dislikes 1

multiplying by .6 is pretty trivial too.

4 months ago | Likes 2 Dislikes 4

it really isn't

4 months ago | Likes 4 Dislikes 2

The amount of time it takes you to find .6 of 87 is an order of magnitude longer that the amount of time it takes you to find .5 of 87

It's really just temperature you need to to learn decently accurate conversion for between murica and normal units. You don't need to know precisely how wide or heavy something is, but you do need to know if you need to pack a sweater.

4 months ago | Likes 3 Dislikes 0

I'd say temperature is pretty similar.

What I wear for temperature doesn't change much over 5 degree F intervals. Maybe around 10 degrees F of inaccuracy is enough to change things. If I estimate a C temperature converting to 81 F but it's actually 75 F, that's not going to result in me being unhappy about wearing shorts because I think I shouldn't have.

10 °C = 50 °F
20 °C = 68 °F
30 °C = 86 °F
Interpolate from there.

4 months ago | Likes 1 Dislikes 0

I've heard the trick Canadians use is "double it and add thirty". That yields results anywhere from "inaccurate" to "wildly fucking inaccurate", but it's close enough for the range of temperatures you're likely to encounter on Earth, at least

4 months ago | Likes 1 Dislikes 0

Well that works for most of my scenarios then

4 months ago | Likes 1 Dislikes 0

That’s a pretty descent approximation, since the actual math is to multiply by 1.8 and add 32.
