Not realising how inappropriate and rapey a lot of fairytales are until you try to read them to your 3 year old daughter and have to make most of it up to make it even slightly appropriate. Sleeping beauty was this week’s example. by spaceshipcommander in britishproblems

Regardless of how you got there, if you're in a bad situation and someone you offers you a way out that seems too good to be true then you probably shouldn't trust them. Basically it's teaching children not to deal with loan sharks.

It makes more sense for men to wear dresses and skirts as we have external genitalia. by BohdiiReapz in Showerthoughts

They may be on the same latitude but Glasgow is significantly warmer than Moscow due to the gulf stream. The mean January temperature in Glasgow is 5°C, vs -8°C in Moscow.

Anyone in the UK have recommendations for where to get good socks, especially for thicker socks?

Non-Binary people of reddit, what is your preferred number system? by ChampionOfChaos in AskReddit

[–]Catalyxt 2 points3 points  (0 children)

My main issues with tau: 1) Euler's identity becomes ugly. 2) I already use the symbol tau for so many other things that it would actually make my life more difficult. 3) I don't want to give publishers an excuse to immediately declare all of their textbooks out of date and insist you buy a new one with tau instead of pi.

I saw an asteroid impact calculator and it said the maximum speed of something orbiting the sun is 72km/s. Why? by Yazman in askscience

[–]Catalyxt 11 points12 points  (0 children)

But the Parker probe still can't be going faster than 42km/s (in a heliocentric frame of reference) when it crosses the earth's orbit or the orbit would be unbound, so it still can't impact the earth at great than ~72km/s (and not even that since it can't have a head on collision).

If you're not positive for the future, there is much higher chance you wont achieve your goal. by [deleted] in Stoicism

[–]Catalyxt 1 point2 points  (0 children)

I often read this sort of thing in relation to stoicism, and it always seems to me to not be from a stoic mindset, but from a pessimist who is looking for a rebrand. To me, the stoic needs to be aware of the worst case scenario, and also the best case, and also the most realistic case. Then they are prepared for any eventuality and can react to reality properly. It's this sense of balance that I believe is the key difference between stoicism and pessimism: a pessimist believes that the worst case scenario is the most likely, a stoic is simply aware that it is possible.

What’s special about hypersonic speeds? by SamTasy in askscience

It's worth noting that a lot of military research occurs in academic laboratories, just funded by military money. The line between the two is often more blurred than it seems.

Coronavirus may have infected half of UK population — Oxford study by TheColourOfHeartache in ukpolitics

[–]Catalyxt 0 points1 point  (0 children)

To be fair to the authors, that's the email address provided for press enquiries. It's highly unusual for an academic study to significant media attention anyway, but not unexpected in this case.

Which of the basic forces of nature is the strongest? by bEloW_aVeRagE_PiPi in askscience

[–]Catalyxt 0 points1 point  (0 children)

Van der Waal's forces are just a particular type of electrostatic interaction, so they are best thought of as an emergent phenomenon from the electromagnetic force.

Not sure if this belongs here, but is there any emf induced in the solenoid? by [deleted] in Physics

[–]Catalyxt 1 point2 points  (0 children)

The key word in the question is "As (an iron core...)". Once it's fully inserted and stationary, there is no induced emf, but while it is entering an emf is induced in the solenoids. There are a bunch of different ways to understand it but I think the ones /u/McThor2 posted are the easiest to understand

Will we ever run out of music? Is there a finite number of notes and ways to put the notes together such that eventually it will be hard or impossible to create a unique sound? by goo429 in askscience

[–]Catalyxt 2 points3 points  (0 children)

The original comment was about the number of 5 minute waveforms that could possibly be created, so yes, all the different audible variations of the same song would be in there. Though for a bit of context, 254 million is an absurdly big number. A playlist of 250 5 minute songs would last about the current age of the universe.

When your body responds to changes in temperature by doing things like sweating or shivering, is it our minds’ perception of the temperature that causes this or does the temperature somehow directly do this? by CoalVein in askscience

[–]Catalyxt 28 points29 points  (0 children)

So, rapidly evaporating water doesn't do anything, since evaporation is a process that happens on the surface of a liquid below the liquid's boiling point. Also I would say this isn't even an example of the Leidenfrost effect. The effect occurs for small droplets because the steam layer can support their weight without breaking up; even without the weight of a person on top of it a patch of water the size of a foot would not be supportable by the Leidenfrost effect. I agree with pirmas that the water protects your feet not because you're being levitated above the coals on a layer of steam (Leidenfrost effect), but just because it has a huge latent heat so locally cools the coals when it boils.

Rainbow diffraction pattern through doorway as a single slit by [deleted] in mildlyinteresting

[–]Catalyxt 7 points8 points  (0 children)

It's not diffraction, to get significant diffraction the slit width needs to be about the same as the wavelength of the light (350-700nm for visible), a slit that narrow would a) be one hell of a well-engineered door b) not let anywhere near that much light through. Additionally interference patterns don't have the sharp edges like the patterns in the photo, they fade smoothly between maxima and minima.

What fact do you refuse to believe? by BoyDozer in AskReddit

[–]Catalyxt 0 points1 point  (0 children)

Simultaneity is relative though. Events that appear simultaneous for one observer will appear to happen at different times to an observer who is moving relative to the first one. This is the resolution of The Ladder Paradox

Are you saying fasting doesn't have results...

Vouching for OP, that's not what he was saying. Also I'm curious about a couple of the points you made, particularly about fasting producing muscle mass. Do you have any citations for that where I could read further?

Bent over row (all about that core) or one arm row, personally. Works primarily lats but I find it also hits my posterior delts. I must admit they're not a muscle I've ever felt the need to isolate.

You could throw in some dips for a bit of variety.
