A biologist friend once told me that many small rodents cannot tolerate certain antibiotics including penicillin.

Thus if this first great antibiotic had been required to be tested as thoroughly as modern pharmaceuticals are we likely would not have it until far later, possibly too late to treat infected WWII soldiers & thus put at rist the allies winning the war.

Same here, used to lose devices all the time to battery leaks. In the last 20 years though I have (outside of where others have used the free "battery included") not seen a single leak.

If in your country you are riding bicycles on the right then having the REAR brake on that side would I think still allow you to use breaking while indicating a maneuver across traffic.

If though you switch them then you would end up applying the front break in such a situation, which considering you would only have one hand on the handlebars could prove "unhelpful".

For motorcycles with turn signals it's not a problem, other than I suppose keeping the clutch & throttle opposite each other.

This LPT apparently bought to you by the alkaline battery manufacturers council.

Most good batteries today should not leak. But for anything you don't use, take out the batteries. I keep them in a ziplock bag taped to the back of the device.

As to recycling, I don't know about other places but here, you cannot just put batteries in recycling. There are places that will take them, but in many cases alkaline cells may still end up in landfill.

I've owned laptops going back to almost that era & in current dollars the price has decreased about 10 fold & quite linearly.

Although it should be said that quality & robustness has gone down commensurally as well.

I did purchase for my SO a Panasonic toughbook some years back which was way more powerful yet only as robust as my early $4,995 Toshiba, it cost me $4,500 in 2010.

I agree partly, but there is a ton of subtlety about signalling a move out into traffic should leave a hand for the rear brake. Here is a good answer to that issue from Quora.

I can't speak to scooters if you mean the modern uprated kids toy device, but for mopeds which were also called motor scooters in the UK the brake layout seems to have settled down internationally to I think rear on left, front on right. But since almost all of these today have turn signals that can be operated by the thumb there is no need to hand signals, see above.

This ☝️ is the best answer, most of the others end up being teleological or anthropomorphic arguments.

An interesting since note is that once a boldly coloured hazardous population is present with its selective predators there is often a secondary evolutionary selection for any mutations that leads to other species beginning to resemble it.

Thus the possible evolution of non-stinging Hover Flys with bold black & yellow stripes that closely resemble those on wasps.

Thank you for this extensive explanation but unfortunately calculation of gravitational interaction in symmetrical smooth objects is I think independent of configuration.

All matter outside of an object's orbit should affect it equally, while that inside can just as well be treated as a point object at the barycenter.

A better answer to the original question is to say that the fraction of dark matter to visible matter within the Earth's orbit is much smaller than that of the sun's orbit around our host galaxy. Thus the latter shows a greater anomalous velocity.

Strictly Moore's law ended a while back unless you allow fiddling with the factors. It was initially a doubling of transistor count every year, which held until 1975, then it was revised to every 2 years until around 2010 when it again started lagging.
