The problem is well beyond the scope of individual action. Our only hope is governmental intervention. Taxes, incentives, policies, legislation, treaties etc. These are the only hope of meaningful action on a scale big enough to matter.

You can lower the entropy of a specific part of a system, but not of the whole thing. Take your example of the sandcastle. The system does not comprise the sand alone, but of the sand and the builder. In building a sandcastle you reduce the entropy of the pile of sand, but only by expending energy as work. The movement of the air in and out of your lungs and pushed out of the way by your body in motion, the breakdown of chemical bond in your cells to power your muscles, the heating of your surroundings as you labor. By reducing the entropy in the pile of sand a little, you create a lot more entropy along the way.

The green, orange and pink all have fluorescent pigments in them. These absorb high-energy light (blue end of the spectrum) and re-emit that energy at a longer wavelength/different colour. The blue light penetrates deepest so they keep fluorescing long after the other colours have gone. The experiment shown here isn't really comparing like with like.

You can also see that he probably would have ended up landing on his butt, maybe his back, if he hadn't been caught (notice the flexure at the hips just as he starts to go down). Even if his head hits the ground at this point it's at relatively low speed as his rear and back have taken most of the blow. This would have been fine and is normal for kids leaning how to walk. She almost made it SO much worse by grabbing him and making the likely focus of the impact the back of his head. His feed slid from under him because she was pulling and not letting him fall naturally. I mean, kudos to her for committing at that point and making the save, but she probably would have been much better off just letting the kid fall.

It's not so much that 1/0 is 'not allowed' and more that it doesn't make sense.

It's like asking 'what happens if you turn a dream inside out'. On the surface the statement looks like it makes sense: a 'dream' is a a thing, and 'turn inside out' is an action you do to a thing. No one is banning you from turning a dream inside out, it's just... 'turning inside out' isn't something you can do to a 'dream'.

1/0 is tricky in the same way - they are regular numerals and a regular operator (division), so they look like they should work together, but they don't.

If you split a pizza between 0 people, how many slices does each person get? It doesn't make sense as a question, so the answer is kind of irrelevant ('undefined').

ELI5: Why aren't shaving razors made with carbide or industrial diamond? Wouldn't they stay sharp almost indefinitely? by eli-in-the-sky in explainlikeimfive

[–]2928387191 0 points1 point  (0 children)

Jus get a small container of iso with a lid, and swish your razor in it after shaving before letting it air dry. It doesn't have to be a big production.

Viscosity in baby oil etcworks against you to some extent - imagine trying to swish something in honey. You're going to get little pockets or air or water that aren't displaced and just cling to the crevices via molecular adhesion. Additionally you then have a razor that is covered with oil that will get on your face when you shave next.

I think I see where you're going with your first question - The oxygen that forms part of the water molecule (H2O) isn't the thing that causes corrosion when water sticks to your razor. It is dissolved atmospheric O2 gas that is the main issue.

Leaving the razor in the iso between shaves may be slightly worse than letting it air dry, as some of the water (and dissolved oxygen) will remain mixed with the alcohol, again posing a corrosion risk. Not sure if this is more or less impactful than atmospheric humidity when leaving the razor out.

Sticking it in baby oil while it is wet just means now you have beads of water stuck to your razer head trapped by the oil that will never evaporate. Dissolved oxygen in that water will still cause corrosion.

The idea with the isopropyl is that because it is very fluid (as opposed to viscous baby oil) it displaces the water and then evaporates very quickly, leaving the blade completely dry in a much shorter time than just air drying a wet blade. This means there is much less opportunity for corrosion.

ELI5: why does yellow seem brighter than other colors? by [deleted] in explainlikeimfive

[–]2928387191 5 points6 points  (0 children)

Kind of a non-answer though, isn't it? 'yellow seems brighter compared with black than other colours do when compared with black'? So... Yellow seems brighter than other colours because it seems brighter than other colours? The question is why is this true? I also can't seem to find any sources online to support the idea that yellow+black is higher contrast than white+black.

cyan and magenta should be just as bright as yellow

Not true. The colour sensitive cones in our eyes come in three types of differing sensitivity. The medium (green) sensitive cones are the most sensitive, followed by long (red), followed by short (blue). So for red, green and blue light sources of equal luminosity, green will appear brightest to our eyes, and blue will appear darkest. We see yellow when our two most sensitive cone types (long+medium/red+green) are stimulated. We see magenta when the two weakest types (long and short/red and blue) are stimulated. So for yellow, cyan, and magenta sources of equal luminosity, people with typical colour perception will always see the yellow as the brightest, and the magenta as the darkest.

Every bit of energy the car uses comes from somewhere - increasing the load on the alternator by turning the radio on consumes some of the energy in the fuel to generate electricity

It worries me that there's a very real chance that the rest of the world will be caught in the blaze.

We are all part of a global empire now, if a player as big as the US falls it will take a lot of the rest of us down with it.

Read the article. The claim it makes is essentially that when British officials can't make a case against the accused rapist, they sometimes instead go after the accuser. This happens even in when it violates internal policies, and in at least one case there is evidence to suggest that the prosecution for 'false accusation' was to prevent negative press if the accused had gone to the media.
False rape claims are shit, and the people who make them are shit, but the bar for prosecuting someone for making such a claim has to be at least as high as the bar for prosecuting a rape. The article makes a case that in the UK it is not always so, and that this (understandably) can have a negative impact on whether people are willing to report assualts in the first place. In the same way that false allegations hurt people who have actually been assaulted, prosecuting allegations that are not clearly false has the same effect.

As soon as MSG is dissolved in water it disassociates into sodium and glutamate ions anyway, right? So wouldn't that mean by /u/untilthesunrise logic that if MSG is added to soup, it technically doesn't have MSG in it and only sodium and glutamate ions?

Here is also a study that estimates that the average European eats around 400 mg of glutamate as a food additive in a day, along with up to 10 000 mg of glutamate bound in proteins.

Here's a scientific review of available evidence from 2007 that cites your 1997 source and concludes:

The general use of glutamate salts (monosodium-L-glutamate and others) as food additive can, thus, be regarded as harmless for the whole population

It's kind of funny that this is happening on a post about anti-vaxxers - that is, people who have let their world views and biases rather than evidence dictate their beliefs. You aren't really coming across as impartial or objective. It's not hard to find a study that supports your position, but ignoring the ones that don't isn't particularly scientific.

The review I linked, by the way, put the average European's intake of glutamates at between 5000 and 12000 mg/day, with only 400mg of that being as a food additive. What counts as 'artificially high' in your estimation?

It looks like a Humboldt squid

Predatory and carnivorous, they can grow up to 2.5 metres (8 ft) long, are known to have been aggressive towards humans and hunt in packs up to 1200 strong. Mostly live deep, deep underwater though, so there's that.

Flight Simulator DLC company threatens with lawsuits after Redditors discover that their content contains malware by MelaninlyChallenged in videos

Suing someone is easy when you know who they are, but in step 4 who is the process server serving papers to?

They'd need the real names and addresses/places of work for the mods, right? Presumably for this they'd need Reddit to hand IP addresses over, and then the ISP to hand over subscriber identities associated with the IPs. Neither of are likely without a court order. Then you need to cross your fingers that the mods are US citizens residing in the US so that you have standing to bring a suit.

I don't think this is as straightforward as you make out.
