Yeah, I skimmed the article. It’s not really relevant. Everything uses technology in some aspect, yet everything isn’t relevant in this community.

Yeah, sometimes you just gotta kill those who disagree.

Respectfully, how is this relevant to this specific community?

Never heard of it before, personally.

Yeah, they never talk about games on YouTube

I think you’re right in this argument, but that’s a tiny smoothie. It’s barely more than a cup.

That’s what’s up. All those old school science shows and classic Discovery channel is a big part of why I got into science / medicine. Learned a lot and got a ferocious curiosity from them.

Hope he explained the water isn’t what’s doing the conducting but rather the dissolved ions within. Pure, deionized water is a fairly good insulator.

Oi mate you got a loicense for that diode

See my comment above with the battery university link, small depth of charge/discharge and frequent cycling is optimal for lithium ion batteries. The longest longevity was many 75-65% cycles, followed by 75-25%, then 85-25%, and lastly 100-25%. There’s nothing wrong with small cycles on lithium ion batteries.

I don’t believe you’re correct. Small discharge cycles are not at all bad for the battery.

Similar to a mechanical device that wears out faster with heavy use, the depth of discharge (DoD) determines the cycle count of the battery. The smaller the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life. The exception may be a periodic calibration of the fuel gauge on a smart battery or intelligent device.

If you look at figure 6, cycling from 75-65% was better than 75-25%.

You’re thinking of keeping the battery constantly charged at an elevated voltage, eg 90-100%. There’s nothing wrong with many small cycles. The most optimal way to use a lithium ion would be many charge cycles and the battery constantly going from 49-51%.

Eternally playing Getting Over It and falling just short of the summit.

It’s very cool to hate on common core.

Alabama and Mississippi teach common core math same as most other states.

That makes a lot of sense.

And yet the states with the highest scores are blue states that teach common core, and Alabama is consistently in the lowest 10-15 states.

The metric referenced in OPs meme is improvement, not raw scores. Alabama improved from really bad to below average. They’re not scoring better than NY or CA.

Alabama’s 8th grade math scores are literally 50th of the 50 states. The only lower grades are DC and PR.

Why couldn’t catenaries handle the power being fed into them? Seems like they’d be able to handle up to whatever the max power output for driving the train is.

I seem to remember some old story about electrified rail going over some mountains and the first run was actually net negative in terms of energy consumption because it was more downhill than uphill.

Pausing time would be worse than living forever. I could not imagine a greater torture.
