| Why do manual and automatic transmissions use such wildly different gearing mechanisms? Posted: 08 Mar 2021 02:01 PM PST I have been watching a bunch of videos on different transmission designs recently, and I am stuck on a seemingly straightforward question. Manual transmissions and automatic transmissions are designed very differently, with the latter using planetary gears and torque converter. My question is: why did automatics switch to this completely different gearing mechanism, vs. just automating the shifts in a manual transmission? I am aware that clutchless and automated manual transmissions exist, but I am not aware of why the conventional automatic transmission design was adopted instead of them. Is this purely historical? (If so, what happened?) If not, what engineering advantages does a conventional automatic offer over an automated manual transmission? (The wikipedia page on automatic and automated manual transmissions did not give me a clear answer.) [link] [comments]  |
| Do Coronavirus variants such as B.1.1.7 produce different antibodies than the "regular" coronavirus? Posted: 08 Mar 2021 01:31 PM PST Is there (or will there) be a way that we could tell antibodies apart from different mutations? Or are the variants too similar to each other at this point that the antibodies do not have a detectable difference? Thanks ! [link] [comments]  |
| how do they measure extremely high voltage? Posted: 08 Mar 2021 05:00 PM PST like do they just stick a bunch of high ohm resistors in series, measure each one and add them up? [link] [comments]  |
| How does the electromagnetic force act on quarks, if at all? Posted: 08 Mar 2021 12:11 PM PST Quarks have a charge right? Does this not subject them to the electromagnetic force? [link] [comments]  |

| Posted: 08 Mar 2021 08:19 AM PST I suppose it is safe to assume that those with open circulatory systems have no way of developing a proper immunitary system. Do all animals with closed circulatory systems have an immunitary system, understood as antibodies, antibody-producing cells and killer cells? Or was there some sort of general imunitary function in every cell (producing all sorts of substances to fight off foreign organisms), which was later given to the immunitary cells?

| Posted: 08 Mar 2021 08:21 AM PST I ask this because I see ALOT of videos that would imply raccoons and foxes are at least semidomesticated but I see a lot of people say "No, that is a wild animal." Also they say there are no truly wild horses let but I've seen horses in the wild, living without any human care. [link] [comments]  |
| What animal grows the least from birth to adulthood? Posted: 08 Mar 2021 08:21 AM PST I thought of this last night and I can't find a good answer on google. Essentially, what animal is closest to being fully grown when it's born? So far my best guess is fruit fly, but again I haven't been able to find any definitive answers online [link] [comments]  |
| Posted: 08 Mar 2021 06:34 AM PST For example, given the formula of water H2O, can we predict its specific weight (under STP), refractive index,... without any experiments? [link] [comments]  |

| Posted: 08 Mar 2021 11:33 AM PST If I understand correctly there is no friction, air resistance, or weight stopping acceleration in barren space (no gravity or anything) why can't I just pull an entire asteroid with my pinky or kick an asteroid 50x my size as if it were a ping pong ball. This question comes from my confusion about how mass operates and effects things in space when there is no gravity. [link] [comments]  |
| What happens to the gravitational potential energy of an object that breaks orbit? Posted: 08 Mar 2021 02:25 PM PST As I understand it, doing the work of raising a ball high in the air gives the ball a certain amount of potential energy (gravitational potential energy to be specific). Upon releasing the ball, the potential energy becomes kinetic energy and the ball falls back to the ground. If instead of raising a ball I was launching a rocket that would break Earth's orbit, what would happen to all the potential energy that the rocket has from being propelled high into the air? Obviously once breaking orbit the rocket still has to have some amount of kinetic energy to keep it from falling back to Earth, but as it moves further from the planet and the gravitational force of the Earth becomes negligible, what happens to the potential energy that was stored in the rocket?
