*Not* an engineer. Engineers look up specs before doing things. That scrubber in the clip is a heavy duty one (the yellow color with green pad is a telltale).

The pan is obviously a non-stick coated one. Which you are explicitly told *not* to use that kind of scrubber on! You are supposed to use the "delicate" ones (which are either blue or pink, depending on brand)

He didn't clean it, he *ruined* it.

Sat, 04:00: Overheard: me: *opens book* me: *sees detailed map* me: hell yes we've got some hardcore fantasy right here http://t.co/2wM6M93GlG

Maybe. All too often it's an attempt. If I had $10 for every book that has maps that were utter nonsense..

I include Tolkien, though it's possible that the *impossible* mountains around Mordor were due to magic, not geology.

But too often you get stuff in places they couldn't be. Not just geology, but weather/climate as well.

As an example, Eastern Oregon (and Washington) are near desert and places like the Willamette have so much rain because the prevailing winds try to push the cloud and moist air masses over the Cascades, and that forces out moisture. Leaving the land east of the Cascades in a "rain shadow".

You see the same thing, only worse immediately East of the Rockies and the other ranges on either side of them. Utah, Arizona, etc.

Compare that with all the fantasy maps that have rich, well watered lands east of a big mountain range.

At least one story that had a swamp next to s desert knew that they had to justify it because it was so unlikely.

*sigh*

Water can be "ice cold" (or "boiling hot") without any special circumstances.

When you cool water, a kilogram drops in temp by one degree C for every Calorie (not "calorie", they are two different units) of heat you remove.

Until it reaches 0C. At which point you have to remove several hundred Calories (the heat of fusion/heat of crystallization) before it turns to ice. Which will *still* be at 0C.

As you continue removing heat, the temp of the ice will start dropping again. At approximately one degree per Calorie. Until you approach absolute zero where things get weird.

Heating water, you get the same thing until you hit 100C. At which point you need an extra several hundred Calories to transform 100C water into 100C steam (heat of vaporization). After it turns into steam, the heat to raise the temp a degree goes back to a low value.

Eventually you hit insane temps and the water molecules break down and then eventually the hydrogen and oxygen turn into a plasma.

But for any remotely normal conditions, this is the way it works.

Super heated water and supercooled water are "special cases". They've gained (or lost) the required energy for the phase change, but things are "quiet" enough to not trigger the change. But a slight nudge and Shazam. Instant state change.

Sat, 07:07: Bernie Sanders finally made it to the mainstream news! I saw it with my own two eyes on the news last... http://t.co/I3kCN8zWVa

He'd been in the news before. Since you *only* watch the news (under protest :-) when you are up her at the right new, you actually have little clue what they actually *do* cover.

Actually, what's more important than the *money* Trump is losing is that he's lost the Hispanic vote. And a lot of other votes as well.

He's unlikely to make it out of the primaries.

Hopefully similar things will happen to the massively anti-gay candidates as well.

Maybe the Republicans are finally starting to implode?
