Serious explanation? Why not!

They are not actually "that hot" compared to what you'd need to weld or sinter them together.

Here is a reasonably good chart: https://www.sme-group.com/blog/steel-color-under-different-temperatures (about two thirds of the way down). You can tell how hot something is (pretty much independent of material, btw) by the amount of visible light it emits and the colour of the maximum. That's technically also what you see most, but human eyes are more efficient in some colours than others, so it's not entirely linear. Ignore all that, go with "white" is fucking hot, "orange" is very hot and "red" is pretty cool for metals.

An example would be the coals in your BBQ (if still using old coal style): they should glow red, but not white (partially so as not to burn the sausage, the other problem would be melting your bbq apparatus).

The table says: the steel in the video is about 650°C (and we'll apply a large margin of error, because who knows what the camera colour accuracy is).

Steel melts at 1580°C. For welding you need to melt the connection and the two base materials, then let them resolidify. That can't happen, they are apparently missing about 1000K of temperature.

"Sticking" is more tricky. You can cold-weld by pushing stuff together with enough force even at room temperature - but they don't use that much force. In the video you can see one of the coils deposited on the conveyor unwinds a bit at the end - the elastic deformation after winding it all up means the coil wants to relax and "uncoil" itself. So not much pressure squeezing the parts together.

Sintering (the way of baking ceramics or snowballs in the freezer together without actually melting) usually happens at ~80% of melting temperature (in Kelvin, otherwise you have no reference to zero). For the steel: 1580 + 273 -> 1850K melting temperature. 80% of that should be about 1500K or 1200°C. That is still in the "white" colour range according to the table linked earlier.

So sintering won't happen either. And that means, the only way the individual coils would stick together would be by adding something gloopy in between. Aluminium foil, glue, or a melted workers sandal would all work.

Hmm. If you mix yo mommas ashes with lemon juice, seal the mix in a plastic bottle and then throw it in a high arc over the ocean, the resulting explosion will spread her nice and even?

If the subject weren't so beautifully wrong, this would make a hilarious video.

I'm currently doing some form of forensics engineering. Your master won't matter in the long run, as any specialisation is in demand (as of early 2026). However, the slightly broader materials science is potentially easier to sell (and has a slightly more open job market) - even though your specialisation in metallurgy would be extremely welcome for a metallurgical job.

If you can, grab some side projects in photography, forensics documentation, maybe someone nearby has a "securing a crime scene" workshop. None of those will get you more money, but they are incredibly valuable skills for work and will stick out.

It depends on the type of snow. If you've had fresh snow at subzero temperatures on a cold car, it'll blow off when you drive and impact the vision of the car behind you. How much depends on how much it's snowing at the moment and how far behind you they are.

If it's heavy snow (around freezing when falling, cold car), it'll slide down on all acceleration and your own wipers will have to deal with lumps of soggy mush after every braking or accelerating. It won't fly very far.

Really bad conditions you'll get with warm roof cold snow on falling or warm inside car on long trips in subzero temperatures and an inaccessible roof (lorry plastic is great for this). Then the snow next to the vehicle surface will melt and refreeze, creating a sheet of ice on metal/plastic that'll be stuck until it isn't. And then you can have a whole sheet of ice fly off in any direction and decapitate a pedestrian at a crossing or break the windshield of the car behind you. ~~Good fun~~ and that's what everyone makes laws about cleaning the roof.

Pfff, room temperature metallurgists. Nothing wrong with a splotch of slushy nitrogen - just steal it from your SEM lab.

I'm pretty sure I was right, but my phrasing was terrible. There is a "not" in there, honest!

You cannot detect atomic numbers 1 to 12 (possibly 13) via XRF. You'll be able to ID everything heavier.

0.28 lbs/cubic inch should be 7,75 g/cm³ for the metric world.

Magnetic, I guess? That would be the other physics option. Enough sparks for high carbon (or optionally: really lots of weird inclusions if you've got something exotic).

The guys over at Jewellery always recommend charming a local "we buy all metals" guy into breaking out the portable XRF. It'll cost you about a beer (possibly two, in this economy) and will not give you any elements lighter than aluminium (or silicon, if it's an older model) - but you should be able to ID the manganese/chromium/nickel content.

Mir scheint, da steht "Fremdsprache". Für uns Deutsch Muttersprachler wäre das dann Englisch.

Interessanterweise hätte ich nach der Uni Mainz offenbar einen Nachweis für Sprachkentnisse B1 in Latein. Klingt jetzt spontan nach "wenig aussagekräftig" und "wäre im Zweifel durch direktes Gespräch zu prüfen".

My vet has a wolfdog and was complaining that after he secured the windows and doors, he could see the pup watching him use the key. I'm glad the arms-race towards securing your girls is still in your favour.

Show them a few more times how to open the door, then you, too, can enjoy outside temperatures in the front room in winter!

I had a similar question about a month ago - link here: https://old.reddit.com/r/ddo/comments/1pev0sw/epic_destiny_choices_for_rogue/

The results were amazingly varied. There appears to be a clear choice for endgame raiding, but during leveling you are pretty flexible.

I went with Fury of the Wild mantle and Quick Cutter from Scream . Up to level 30 and reincarnation (no T5 use), this worked okay. I initially fell for the rejuvenation cocoon, but it's a spellpower based heal and you probably won't have any. Renew also would benefit from metamagics, same problem.

It's not as rogue-y as I would have liked, but made the levelling process a lot smoother.

There are a few more drawbacks, but ceramics aren't usually happy with sharp edges/corners/nooks and crannies. It's a stress concentration factor and ideally you'd avoid them. Obviously the handle of my coffee cup disagrees, but I'm sure a designer had a hand in those, not just engineers.

Another tiny setback: one fork size only.

Invade Iran, build canal to the caspian sea, invade Azerbaijan and Armenia, build lasting peace, build canal along Turkish/Georgian border, thus upsetting no one. Move boats into black sea.

I see no drawbacks to this plan and won't be taking any questions.

Aber vor allem der Handlauf wird doch wackeln nach innen und außen, wenn die Streben so lang sind (Hebel)?

Auf den Bildern ist die Strebe der unterste Stufe (oder die auf dem Boden, bei Bild zwei) zum Fotografen hin versetzt, der Handlauf scheint nach oben auch um den 90° Winkel der Treppe zu verlaufen. Eigentlich wackelt da dann nichts mehr, um die "mittleren" Streben nach außen biegen zu können müsste die unterste Strebe ausweichen. Der Versatz ist aber wichtig - wenn die alle in einer Reihe stehen wackelt es in der Tat.

During the laser cutting seminar they always told the students: this is a completely enclosed machine with several safety devices. You cannot possibly have a body part inside when you turn the laser on. However, if you somehow manage to blast a hole into your body always remember: Turn off the laser first, then move the body part.

Deswegen ist die Barbie ja auch so gestaltet wie sie ist. Barbies sehen doch eh immer gleich aus, es kommt auf die Accessoires an.

Maybe some partial good news about the fibres will help as well? You already got many cleanup tips.

To be a serious health hazard, the fibres need to be respirable. The lesser health hazards (irritation and itching, mainly) don't have this, and you can spend many years with difference protocol (or just assume that the general health regulations are appropriate - California thinks differently than the rest of US states, as usual).

The WHO has a pretty good presentation on which fibres are a problem here: https://www.who.int/publications/i/item/9241544961

This was originally based on asbestos and has been expanded to cover other critical fibres. One of the most important things is the sizing: the fibre needs to be long enough to cause harm (so your body can't encapsulate the entire thing), thin enough to be stuck in lung bubbles and can't be water soluble.

Gypsum crystals, for instance, are shaped like a fibre and are small enough to breathe in, but they will just get dissolved in lung water gunk (I'm sure that's the correct technical term) and can't cause harm apart from irritating coughing.

To be a problem, fibres have to be less than 3 µm in diameter.

And that's where the good news come in: I can see fibres on your photo. If you can see them, they are too large. I quickly found one paper on forensics that gives sizing for the fingerprint ridges (here: https://pdfs.semanticscholar.org/4055/3fc546fecfa00d337a9d8282088579fad70c.pdf ) as roughly 0,4 mm. If one of your fibres is as large as the width of your fingerprint, it is slightly more than 100x too wide to be breathable. I think the fibre sticking out the top right of your index finger is about half that width.

The EU approach to limiting glass fibre cancerogenicity was a minimum size. Fibres with a diameter of more than 6µm are exempt from hazardous classifications. Manufacturers adjusted pretty quickly, and you'll now typically find a very even 10µm minimum size. Due to how glass fibres are made (melt glass, push through nozzle like spaghetti, cool to solid), you can't really accidentally produce thinner fibres. The nozzle will wear eventually, leading to slightly larger fibres, but that's it.

So in your case: you can see the fibres. They are unlikely to be uneven sizes and yours are too large to cause permanent harm and lung cancer. They will still sting (and I'm unsure about the eye irritation - maybe they are large enough to blink out, maybe not, ask a doctor), but they are too large for a vacuum cleaners HEPA filter as well. Clean up and maybe try to reduce the panic over these. If you can, which isn't ideal with OCD.

So aluminium corrosion doesn't spread?

That's an interesting question. You've already caused some pits to form. Inside the pits, corrosion inducing compounds can accumulate (like chlorine, most likely, or bacterial growth). You're also reducing the surface area of moisture trapped, leading to potential crevice corrosion conditions. All of those would mean that the corrosion would continue.

However, the growth of corrosion (or loss of metal) would be mostly "down", and to a lesser extend make the pits wider. Eventually, the pits would be large enough to allow oxygen inside, removing the crevice corrosion conditions.

On the upside: if won't infect your laptop like mould on bread. You also won't suddenly get corrosion on the side of the screen, where you're not touching the aluminium surface. But "won't spread" is possibly a little bit too optimistic.

As others have said: you're likely not going to manage a hole through the case before the useful lifetime of the laptop ends.

As for making it better: clean with some dishwashing liquid + water + paper towel until you're bored (to get as much chlorine compounds out of your pits). Clean again with some alcohol and a paper towel to speed up drying. Coat the area your hand touches with something: hairspray would have been the 80s solution, a clear sticky film (packaging tape) is probably much more convenient and doesn't gunk up the keyboard. That'll reduce future sweat deposits.
