Let’s do it:
The phenomenon that causes divers to be trapped is called differential pressure, or Delta P. It requires surprisingly little Delta P to trap divers in such a way that they can’t free themselves.
The formula is simple: F=Δp⋅A Δp = Differential pressure, A = the area the differential pressure acts on, in our case the cross sectional area of the pipe.
#Example
30 cm pipe => A = π⋅(0,15)² Delta P only (!!!) 0.1 bar (= 10 kPa).
F = 10,000 Pa ⋅ 0.07 m² ≈ 700 N. This equals roughly 71.38 kg of weight.
#Now, let’s try this with the numbers above. Unfortunately, we don’t know the diameter of the pipe so let’s again assume 30 cm.
Δp = 21.375 - 14.7 psi = 6.675 psi ≈ 0.46 bar = 46 kPA
F = 46,000 Pa ⋅ 0.07 m² ≈ 3250 N. So you would be sucked to this pipe opening with a force of roughly 330 kg.
#For fun, let’s assume a 50 cm diameter pipe:
F = 46,000 Pa ⋅ 0.196 m² ≈ 9020 N. This equals roughly 920 kg of pressure.
There is absolutely no escape here and I think it’s safe to assume the diver would be sucked through that pipe.

As if denying millions of Americans access to proper healthcare wasn’t enough, they appointed an anti-science, anti-vaxx idiot as if to make sure even more harm would be inflicted on them.

Here’s my theory: All diplodocuses, much like all brontosauruses, are thin at one end, much MUCH thicker in the middle, and then thin again at the far end. That is the theory that I have and which is mine, and what it is too.

If this comment saves only one person from wasting their money, it is worth it:
Do not buy Focal Bathys.
The build quality is super cheap, mine broke not even two years after purchase. The plastic surrounding the metal bits that connect the central part to the ear pads will break sooner or later.

That’s awesome, man. Huge respect, I know how hard it is. I was very lucky to somehow get out of my debts, and it really gave me back an inner peace like I last felt when I was a teen without any obligations.
Life isn’t perfect, but hey, it never is. But I can at least take out my wife for a fancy dinner each wedding day and I don’t feel like a total loser anymore. Keep going, even if life throws shit at you, never ever give up.
- Comment on What brings you peace in your life? 2 months ago:
I’m not good with people as well. You can’t solve all your problems at once, but you can take some weight off your shoulders. Every bit helps, every small step forward gives you a little more energy, a little more emotional wiggle room and belief in yourself.
Not gonna lie, it’s not easy. It took a long, long time for my brain chemistry to readjust so I could feel joy again from something else than weed. And I’m not sure if I could have done it without help from family and friends (the very few that I have).
But I am so glad that I somehow made it. You will be, too. I root for you, my friend, and I wish you well.

I hate to be that annoying fuck who mentions having money to get by.
But I have been broke for such a long time (until I started working on getting my life back on track), I even once got evicted from my then relatively cheap apartment in Berlin. I spent all the money I had back then on smoking pot. Tried getting away from my problems, mainly caused by being broke, by being stoned off my face 24/7. You can imagine how that went.
So yeah. 15 years later, having saved enough so I don’t have to worry about these things anymore is a huge deal for me.

That may be true, but in case of the Cybertruck, I doubt that there is any lipstick you can put on that particular pig that can somehow turn it into something I would even remotely consider buying.
I mean, I’m European, I can’t buy the fricking thing anyway, but I am also rather glad that I’m spared from ever seeing it in the wild.
- Comment on 2 months ago:
Leaving all the downsides of the Cybertruck aside - the fact that it’s built by a fucking nazi, the fact that it can turn in to a death trap, the fact that the build quality is shit…
Who the fuck buys a hideous, hideous car like this…? Who suffers from such poor taste that they think a piece of junk that looks like it was designed by a five-year-old is something worth spending money on, let alone so much?

As much as people enjoyed Waltz’ performance in the opening scene and how utterly menacing and ruthless his facial expression was when he asked the Frenchman “You’re hiding enemies of the state, aren’t you”, can we all just take a moment to appreciate how he also pulled off looking exactly like the pathetic human being he portrays in this very image?

In Germany, we have the word “schönsaufen”, which means something along the line of “drinking until something or someone ugly looks pretty” and I think that’s beautiful.

I gamble too, but I do it with knockout options. I sometimes buy a factor 20 option, set it to 5% trailing stop loss and watch what happens.
In many cases, the option starts losing value and is automatically sold once it’s lost 5%, which isn’t too bad if you’ve invested, say, 1000 €. You lose ~50 €.
In other cases it goes up. And up. My current high score is making 450 € with one such investment.
It’s fun, and not too risky. Meanwhile, my retirement vehicles go brrr.

I started investing during the corona dip. Best financial decision of my entire life. These days, it’s an extra 20% effortless household income and the entire portfolio value is up almost 40%.
But even then, I felt I was just too late to the party for going into crypto. Thank goodness.

So here’s a quick recipe for a spicy egg salad. It’s a kind of love it or hate it thing.
20 cooked and roughly chopped eggs 1 jar of Hellmann’s Light mayonnaise 1 jar of white asparagus, chopped 1 jar of mushrooms 50g Stokes Curry Ketchup 3-4 dashes of Worcestershire sauce Habanero Tabasco to taste
Has the same musical effect on your digestion.

Absolutely. When I go to a bar or restaurant, I prefer a place that doesn’t look like a co-working space. Also, when I see anyone using a laptop in there, I’m out.

When I was a little kid, one of those flying cunts stung my brother. So I declared war on them.
Over the years of my childhood, I caught dozens with my net. I held the landing net in front of a cross spider’s web, so that the wasps, triumphantly but mistakenly believing they had gained their freedom, had to fly straight into the web.
And then I watched those little assholes get destroyed. I’m pretty sure that to this day, I’m worshipped as a god by the local cross spider population.
