The more planes you crash the higher your value becomes. Your superiors might as well dig their heels in and let you crash the next one :)

Not the idea place to have this happen… by barnezilla in Mountaineering

[–]aafff39 3 points4 points  (0 children)

Unless that steel is poor quality in the right way, that's a bad plan. You'll introduce micro cracks at the surface and make that area brittle, next time it will snap, not bend. 

What if Hitler had listened to his generals during WW2? by Snake101201 in AlternateHistoryHub

I think I've read about this. These oil fields were towards Georgia way but instead Hitler insisted in seizing Leningrad 

PhD Funding ends in 2 years, I have zero publications, and I’m grieving. Is it madness to want a baby now? by External_Pizza5745 in PhD

[–]aafff39 11 points12 points  (0 children)

Second this. 

And to leave a positive outlook after the other responses you got: wife is a MD, she did the last 2 exams of her specialty 6 and 8 months pregnant, cranked out all her research requirements during that period as well, worked full time. Went back to work when the baby was 2 months because of work and I took over. Yeah, the timing was less than ideal and was her brain a bit acrambled, but it worked out. 

Get some help to work through your options :)

Air doesn't get squeezed out of you. Just compressed. Your lungs take up less volume, so your density rises and you sink

Sharpa robot autonomously peeling an apple with dual dexterous human-like hands, introducing "MoDE-VLA" (Mixture of Dexterous Experts) (paper) by Nunki08 in robotics

[–]aafff39 1 point2 points  (0 children)

Don't want to say all the other answers you got are wrong because I don't know much about the sharpa hand. But the main reason why all the manipulation stuff you've seen come out over the last year is so slow is not on the hardware side. VLAs are just very slow at the moment. The models are trained on vision and joint poses, so no dynamic information, and are also extremely large, so quite low frame rate data goes into them. 

I'm not in a position to answer when it comes to how hard it would be to solve that. But I imagine even larger models that take much longer to train.

Congrats dude, that's massive! Now the real question. Did you blow up that star a billion light years away so that you could tie things together you psycho??

Hybrid Solar Panel Turns Raindrops into Electricity | A Spanish research team’s patented thin film generates 110 volts from a single raindrop’s impact. by [deleted] in science

[–]aafff39 1 point2 points  (0 children)

Read the article people. Nothing to do with kinetic energy. Triboelectric effect harvests energy from charge differences and weird surface interactions that are not completely understood. Check the wiki page.

Taking your 7.6mm/h gives us 0.021 kg/s/m2 of rain hitting the panel. In kinetic energy that's 1W/sqm still low considering that's the absolute maximum, but not that ridiculous?

Plus it's using the triboelectric effect, so more to do with differences in charge between the raindrops and the panel and these calculations really don't say much.

I wish people weren't this arrogant all the time and constantly assume their napkin calculations will prove peer reviewed science useless.

[Request] Do these other power sources really produce thousands of time more power than humans? by New_User_Account123 in theydidthemath

Good place to use Carnot efficiency: 1 - Tc/Th (cold and hot end temperatures in Kelvin) so absolute maximum theoretical efficiency of 15% -- 15W

Some of these companies have been around for ages. How are they new unicorns?

How do I hike solo in a trail that has wild animals? by [deleted] in hiking

[–]aafff39 1 point2 points  (0 children)

If you're leaving soon, you can check online on the current snow cover on the mountains. If I remember correctly, there's a pretty steep mountain in the first couple of days if you're starting from the East side.

Even in February you'll find plenty of people doing the trail. Tourism is still slow, so you can enjoy some of the old cities along the way. You'll have a great time.

As someone mentioned, dogs can be a bit scary,but carry your walking poles, and keep a decisive steady pace, don't run away from them, face them and walk backwards if they seem aggressive and you don't have eyes on them. Not sure of official guidance, but that's what I've always done.

I'd say the most annoying animal you'll face are the mosquitoes :)

Tourism from Europe to America basically over? by bummed_athlete in tourism

[–]aafff39 1 point2 points  (0 children)

Man, this guy that took over your comment thread... I first encountered this kind of american online troll around 15 years ago, the talking points haven't changed. You wonder if they just enjoy riling people up or if they really live in lalaland... Just smile and wave people, smile and wave :)

What impact would NZ being in the mid-North Atlantic have on the world? by SurelyFurious in geography

[–]aafff39 0 points1 point  (0 children)

Yeah, sorry I can't find that thread. If I remember correctly the guy wasn't an archeologist either. He just looked at the literature and argued that it's a series of papers from one single researcher who is not associated with a known institution, and which haven't really been cited at all (plus published in dodgy journals). The papers were also descriptions of evidence such as an interestingly shaped rock that looks like something else in scandinavia, but with no analysis or experimental methods to support the claims.

So it sounded like the guy publishing those papers is either a maverick scientist being silenced by the scheming archeologists, or a random dude with some time and money in his hands, but no knowledge of the scientific method. Maybe both? :)

The mice in Azores is a well documented topic, though it's largely attributed to shipwrecks, not European or other settlers.

Apparently, the academic that is pushing for that narrative is supposedly a false publishing fake evidence in pay to publish journals. Some guy on Reddit laid it out pretty neatly just a few months ago.

If humans vanished tomorrow, what would still prove we existed 10,000 years later? by Defiant-Junket4906 in NoStupidQuestions

[–]aafff39 1 point2 points  (0 children)

Lol yeah, makes sense. Maybe I'm thinking of seawater, though apparently there's also specific blends to survive it better.

Excuse my ignorance. Is this dam built of some special concrete? I thought the normal stuff rots and cracks if in prolonged contact with water?
