1. Microwave yourself to obtain radioactive DNA sample

2. Scrap four nasal samples into four tubes and treated with chemicals like acids

3. Do some jello stuffs the scientists do

4. X-ray the jello piece

If the jello shows lines in more than 2 wells, you have corona virus.
Please proceed to report yourself to the local emergancy unit and stay 6 feet away from the computer to avoid 5G virus spreading.
Clean your hands with soap upon touching frequent areas like the pp.

If there are no lines shown from the jello, you don't corona virus. You're probably crippled. So monitor your health daily to be alerted to possible symptoms to corona virus such as fever, tiredness, constant coughing or lost of smell.

Every time I solve a problem he has to go on about how my method was weird, long or unusual, why can't he just shut the fuck up if the proof is right? What more is there to say? What is it to you that I made my proof by contradiction instead of by cases?

I'll never forget when he asked us to prove that [math] \int_{a}^{a+{\pi}} |sin(x)| = c [/math] for any a, and he gave me shit for proving [math] \int_{a}^{a+{\pi}} |sin(x)| = | \int_{n{\pi}}^{n{\pi}+{\pi}} sin(x) | [/math] first by fucking around with the absolute values.

Though I've heard from people I know with very high tolerance they still have dreams. Cutting out weed like the other anons pointed out is important. Another option is high zinc+magnesium+melataonin before bed, if you don't dream on these supliments then you've got some seriously fucked up repressed memories your subconcious is blocking you from, as it's known that everyone actually does dream some people just instantly forget their dreams.

I remember one tinfoil guy working on a wormhole/zero point energy machine. We were kind of friends cause I was the only one not calling him crazy or throwing pebbles and shit at his house/car. One day his garage was emptied and he was gone. Car, house - all that stuff was there. I think I remember hearing about the cops looking for him.

The more time goes on and the more batshit like this image I see the more I think he might have actually succeed in his project and I somehow ended up in the fallout sent to the shitverse.

The low gravity, low population density and lack of infrastructure would make mars compatible hovercars very attractive to look into for sure and since there's no roads or downforce, thrust would make viable solution to direction and speed changes.

I'm not sure if we'd be talking about "air" cushion, or actual hover technology with vertical thrusters. The later one would make more sense earlier on before routes were cleared of boulders.

Part of the problem is that the line between physics and chemistry has really gotten blurred--to the point that there's not a meaningful difference between the two anymore. More often than not, important chemists nowadays are also physicists and engineers, so the branding is all off.

This is the work of a designer. Not an engineer, a designer. Projects of this scale have design teams and committees. They didn't put a pair of features on it which speak the same design language, or any design language at all. Even the texture and colour couldn't have possibly been chosen any worse. If it was like some seamless white blob it would have even been easier to clean and more visible.

One example, the base of it is slimmer before the cut-out than the head. Every normal thinking person would have made these two sections the same width

Then again the lights, shape, positioning and colour are all horrible and the panel gaps look insanely cheap. Hell even construction site toilets look better built than this thing and this is meant to operate among customers.

This is pretty good, but I think my real issue is not knowing how much radiation there is in any given region of space. Increasing thickness by X amount reduces the radiation by half, but if I don't have any idea how much radiation there is to begin with then it doesn't mean dick.

Does anyone else ever wonder about what there was before the big bang? It kind of seems ominous to me, because we don’t actually know what there was before it. People always talk about how we’re replaceable and meaningless in the grand scheme of the universe, but how do we know that the universe itself isn’t replaceable, that one day the big bang will go off again and our universe will be destroyed, most likely replaced with a new one? Are there any remnants of things before the big bang in our universe?
