infinity is not a number, it's an idea. so you can't have infinity plus one, or infinity divided by two.

if you count 1, 2, 3... and never stop, you'd never get to the end, because the series is infinite.

the kicker is that some infinities are bigger than others. consider the set of positive whole numbers or integers above. there's an infinite number of positive whole numbers. but there's also an infinite number of even numbers, and an infinte number of odd numbers. and the infinite number of whole numbers is clearly bigger than even or odd ones.

fun times, right?

if regenerative braking does half the job, only half of the heat is generated by the mechanical brakes, and half the cooling is required.

> Evs also have brakes. They just have 2 sets. Motors and brakes.

while this is true, because of regenerative braking, the hydralic/mechanical brakes aren't at as much risk for overheating and therefore do not have the same cooling requirements.

as with everything else, optimization of cooling versus aerodynamics is required. and with electric vehicles and regenerative braking, aerodynamics can be prioritized more than with your typical ICE sportscar, where braking performance and cooling is prioritized.

or isopropyl alcohol which is much cheaper lol. shake it a bit after.

chairs that have less moving parts are inherently stronger. sturdier design with thicker structure will be stronger too. I'd look for a chair that has a non-adjustable back with sturdy framing.

your requirements are very specific and best done with in-person shopping. i'd look into herman-miller, recaro, and the other well-known brands.

flight case with heavy duty casters perhaps. or a samsonite lol.

​

but honestly, r/onebag is the way I'd go. no chance of lost luggage.

nothing is gonna fix that other than a parachute lol.

the other way is r/Leathercraft and DIY one. it will be the best one you've ever had because it's handmade for you, by you. do a search for 'wallet' or 'card holder' and snoop around. I'm sure many of them would do a commission and make one for you, or, again, you can DIY if you need another hobby lol

so many options exist because so many preferences exist. thickness, softness, etc.

have you tried memory foam pillows? I haven't slept better in years.

the commercial stuff is definitely sturdier and longer lasting.

you get what you pay for with dollar store stuff.
