They’re different numbers. Base 10 isn’t perfect and can’t do everything just right, so you end up with irrational numbers that go on forever, sometimes.

Fractions and base 10 are two different systems. You’re only approximating what 1/3 is when you write out 0.3333…

The … is because you can’t actually make it correct in base 10.

1/3 is rational.

.3333… is not. You can’t treat fractions the same as our base 10 number system. They don’t all have direct conversions. Hence, why you can have a perfect fraction of a third, but not a perfect 1/3 written out in base 10.

Do that same math, but use .5555… instead of .9999…

Except it doesn’t. The math is wrong. Do the exact same formula, but use .5555… instead of .9999…

Guess it turns out .5555… is also 1.

If you can’t do it without fractions or a … then it can’t be done.

You’re just rounding up an irrational number. You have a non terminating, non repeating number, that will go on forever, because it can never actually get up to its whole value.

I’d just say that not all fractions can be broken down into a proper decimal for a whole number, just like pie never actually ends. We just stop and say it’s close enough to not be important. Need to know about a circle on your whiteboard? 3.14 is accurate enough. Need the entire observable universe measured to within a single atoms worth of accuracy? It only takes 39 digits after the 3.

X=.5555…

10x=5.5555…

Subtract x from both sides.

9x=5

X=1 .5555 must equal 1.

There it isn’t. Because that math is bullshit.

They’ll just flash the computer to default to be 4th gear upon signal loss instead of 1st gear. Danger problem averted. Cost is only 30 minutes of labor.

That article you linked is utter trash, but it is correct about battery weight of a charged battery…technically…very technically…barely.

Like, a 4,000 mah lithium battery fully charged should weigh about 30 picograms more than when dead.

To put 30 picograms into perspective; a single 5 inch long human hair weighs around 0.04 grams. Well that’s 40,000,000,000 picograms.

Then they’d have to pay them more.

There’s still tons of places that police, firefighters, and EMT’s, like $35k a year starting. Everyone always talks about teachers not making enough, but forgets about the people who show up in 5 minutes in the middle of the night because you called 911 and have no idea what to do and need to get help fast. Firefighters and emts are exploited because of a love of the job and what it means to them. Police are often not of that same track. If you don’t want to just attract the guy who wants to walk around looking for trouble and have a gun, you’ll have to make it worth the money.

There just needs to be a cemented in place ban that can’t be undone for at least 20 years.

There’s nothing being made in the US for batteries because you can’t beat China in price and companies aren’t going to put six billion dollars and 5 tears of construction I to making a battery factory if they don’t believe the ban would last long enough for it to be worth it.

Possibility for private planes, but none for commercial planes. Just imagine a commercial passenger plane or cargo plane that needed a giant amount of electricity and like 12 hours of charging in between every flight.

Then, for safety reasons you’ll need to have two batteries in case one goes bad.

Googles find my device network has been live for a couple of months now, after it was delayed (supposedly waiting on Apple) for like a year. Two other companies released trackers around the end of March. There’s a few more sold in non US markets. Moto saying they’ll have a tracker for sale in the coming months while others have already left the gate would be the slow poke part. There was a huge amount of info about the find my device network rollout. Moto really should have done this and been selling it already. It’s a copy of what’s already available.

There’s no evidence that time started at the big bang, either. So it’s silly to say.

Once again, I did this for a living, for a decade. We would constantly have cars with failed batteries, we would bring them in, charge them up, test them, they would pass, we’d send them on their way, and they would fail again

I also test batteries and this just looks like you all didn’t test them well. Like you skipped the capacity test because it takes being hooked up for a long time instead of the test that takes 20 seconds to do.

What I meant by “what if it wasn’t the first big bang?”, was that what if it wasn’t the first of our own universe? I mean what if space will at some point stop expanding and start contracting. Pull everything back close together again. Then theres another expansion just like what we’re currently in now. The best scientists, physicists, and mathematicians haven’t been able to work out a lot of major thing about our universe or how it works or even if it’s flat or folded in on itself yet. The data and tests/measurements don’t exist yet. So until that can get worked out into a theory, it’s silly to say time began at the expansion.

Physicists don’t even know why it started expanding to begin with. We also don’t know if there’s anything outside of our own universe. We also don’t know if our universe is curved and folded in on itself, which would make several mathematical calculations for the size of the universe and what was going on with expansion a bit easier to try and work out (I’m also not a physicist. These are just things ive read about) or if it’s flat. Their best measurements right now is that it’s flat. But they still aren’t sure, because they don’t know how big space actually is right now. If it’s big enough, it could still be curved in on itself, but we just can’t measure the flatness of two points far enough apart from each other to notice the curve. An example I given was that it would be like trying to show the earth was round by measuring an area of a sandbox.

There’s no evidence to point to the big bang as being the very beginning, though. There may well have been a billion big bangs before this one. Each one taking so long to reset and start anew that to us, it might as well be seen as about infinity. Humanity outright doesn’t have the knowledge of what happens on extremely large or extremely small scales. We don’t really have a clue for what actually made space start to expand in the first place, so we don’t know if it’s ever happened before, or even if it happened anywhere else at any other time but outside of our observable universe.
