Is there an evolutionary advantage to leaves changing colors in the fall?

That sounds.. very unnecessary and wasteful to manufactory disposable electronics for that purpose.

Depends on the degree we open with

Someone mentioned something about black balls as well?

"better not tell you now"

You can for sure have infinite numbers plus one, or divided by two.

Those kind of numbers are called transfinite numbers (ω, ℵₒ, m)

They are not finite, just not absolutely infinite (∞).

But a transfinite number t + 1 is, well, (t + 1) and t / 2 is (t / 2)

Which is not the case for ∞ + 1 or ∞ / 2 which both are still ∞

Maybe I shouldn't go into transfinite numbers in eli5...

You are correct. Your brother's mistake is that he thinks cold is somehow stored up, and that freezing it longer adds to the amount of cold in the meat.

But once the temperature reaches equilibrium with the freezer, it is the same whether it's in for a day or a week or a year.

Coldness is a subjective quality for something that has less heat than something else. There is no cold substance.

The only way the day-frozen vs week-frozen would thaw faster is if the day-frozen wasn't actually frozen all the way through yet (very likely). If two identical chunks of meat were frozen all the way through, they would thaw at the same speed.

If meat has been frozen for a looooong time (and freezer burned), it would actually thaw faster, because is has less frozen moisture in it after the freezer burn has dehydrated it.

They do! They are the digital ones that usually say Yes+ or No- So they definitely make them. Clear Blue Easy or most generic brands are available but be prepared to shell out a few extra bucks for the tech :)

Assuming it has been in the freezer long enough to completely freeze, it shouldn't make a difference. If I have 2 ice cube trays and I put one in the freezer for an hour and the other in front day, the ones that were in there for an hour haven't completely frozen yet, and will therefore melt faster, but if I instead compare ice cubes that were in the freezer for a day and a week, both had enough time to completely freeze and there shouldn't be a difference.

Only if it's something huge and doesn't fully freeze.

Frozen is frozen. If they are at the same temperature throughout and the same weight and mass they will that the same whether frozen for 24 hours, 24 days, or 24 years.

You're mostly right with some technicalities:

1. If the item in question was not frozen all the way through after one day in the freezer, it would indeed take longer to thaw if left there for a week instead

2. Extended freezing, especially in a home freezer, dehydrates food. This could cause it to take longer to thaw, depending on the circumstances of the thawing.

Yet you still haven’t answered my questions. ……I give up.

I didn’t say they were the only people joining, but it was a swell in the ranks for sure, and those are the ones that have died or are dying out without that volume of replacement

Same reason why US only cars have descriptions next to the wipers, lights etc. and international brands use symbols

On top of what others have said I'm gonna throw in that we made new technology faster then we made new strategy's and we once starting fighting and tanks and gas and other weapons were used and it became a stalemate and going over the top and throwing bodies at the enemy is a tried and true method. We do see near the end of the war new strategy's used by German stormtroopers who used in infiltration tactics on weak parts of the allied line which would then pave the way for regular infantry to exploit the disruption in the allied lines.

A firewall is either a piece of software or a physical device that protects an network or a PC/Server from unauthorized access.

The name comes from Firewalls in Cars or Houses which are physical barriers meant to prevent fire from spreading into the passenger compartment or into an adjacent room/house. Like a Firewall in a car a computer Firewall prevents malicious activity from coming into your network from the internet.

The most basic firewalls look at port traffic coming to a device and stop unsolicited traffic. ie any traffic that is trying to access a port that shouldn't be accessible to a hacker.

More advanced Firewalls are called NGFWs (Next-Gen Firewall) or WAFs (Web Application Firewall) that actively look at packets and traffic looking for signs of malicious activity and stop it before it goes to a server.

Yeah, you can paint an infinite area with a finite amount of paint.

The area under the curve 1/x from 1 to infinity… infinite.

The volume of the curve 1/x from 1 to infinity revolved around x-axis… finite!

The area clearly fits inside the volume!

But then you need to consider practical issues like the size of the atoms and molecules that make up the paint.

> One can't "count" all of the decimals because you can always pick another decimals between A and B.

This is unrelated to "counting". The rationals satisfy the very same property, yet can be counted. But all decimals, i.e., real numbers, cannot be counted, they are "uncountable".

Conversely, there are uncountable "discrete" ordered sets where nothing is between a number and its two neighbours. Hence the property you speak of and being (un)countable are independent, neither implies the other.

This. "Infinity" has different meanings or interpretations depending on the field (mathematics, physics, philosophy, ...), context (sets, numbers, size, mind, ...) and much more. In other words, there is not the infinity, and listing&explaining all available options would be almost impossible, and definitely too long.

>So you were really only left with a creeping barrage or a mass formation running to the other line.

I was going to make a technical and slightly pedantic point, but I've realised it might be one that illustrates something important about WW1 that /u/Version2dnb might be interested in.

What is a creeping barrage? A creeping barrage is an artillery barrage that moves forwards at a slow, steady pace (typically in 50-100 yard increments). If your opponents are sitting in some trenches, why not just keep hitting those trenches rather than moving your barrage?

A creeping barrage has three main goals: to keep the enemy's heads down while your own advance, to prevent reinforcements advancing or defenders retreating, and to throw up smoke and dust to cover the advance.

It "creeps" forwards so that it stays ahead of your own troops as they advance. There's no need to communicate with the artillery to say "we've reached this line, move the barrage", something that was difficult to do in the early days of field telephones. The troops just have to stick to the timetable of the barrage.

Of course, "just stick to the timetable" is anything but easy. But the whole idea shows how armies were trying to figure out ways to use combined arms and to deal with the problems they faced on the battlefield. Techniques for barrages became increasingly complex and effective as the war went on.
