/sci/ - Science & Math

Anyways I will leave the project blogs up but probably won't update from now on. I may have to take them down, too, if something like this happens there. And obviously I can't post here anymore. I am really sorry I realize what a bitch move that is but I can't take much punishment. I'm weak I guess.

I really enjoyed talking about the ocean with you guys. I am going to miss it.

>I hope you get sued for slander and lose everything you have.

I'm pretty sure he got my email from a thread where I explained why I wasn't gonna sue that guy from Reddit for the cereal guy shirts he's selling. I am not litigious in general.

Anyway if people want to hurt me for any reason it's probably because I've done something to deserve it and should let them carry on with it until they are satisfied.

Well the damage is done now. I appreciate it but I still have to leave /sci/. I don't see how I can post here anymore. Which is a shame as I love the community here and sharing my enthusiasm for oceanography and hobby projects with them was one of my major coping mechanisms. I don't really know what I'm gonna do from here on out.

>>4670342

Yes. Although I may have to move again. Online and phone harassment made it necessary to leave Florida. I don't know what I'm supposed to do. I feel like eventually I'll have to die.

This doesn't matter. A lie gets around the world seven times before the truth can get its pants on. The ED page, and images like OPs, are powerfully damaging even though they can be quickly debunked. Having seen others destroyed in this way I admire his skill at it. There's literally nothing I can do to defend myself. I don't know what to do now except be miserable and regret existing.

Op's image is photoshopped.

Please, stop this. I have never done anything like this to anyone else and never would. To my knowledge I have not wronged you. I don't understand why you'd do this.

>>4670059

OP, I don't know why you hate me but I am open to the possibility that I deserve it. If you set out to hurt me, you've done an excellent job. It isn't hard to do. If you think I am full of myself because I share these projects on /sci/ you're mistaken, I fully understand I am a shitty person. These projects are all I can do, it entertains me and makes me happy. I just wanted to make a positive contribution to the board.

If at some point in the past I said or did something to you, specifically, to provoke this please tell me what it was. I don't ever want to make an enemy out of anyone where it's avoidable.

On the other hand if you're simply determined to cause me suffering because you enjoy it, there's nothing I can do to stop it and I suppose I'll just sit here and absorb it until the thread 404s and then leave. For the sake of your satisfaction I would like to confirm that I am very ashamed, suffering immensely and you've done an excellent job reopening old wounds and pouring salt in them. You're very talented at this, I feel miserable right now. Continue I guess.

I should also add, although I assume everyone already figured it out, that the OP's image is photoshopped. Unfortunately nothing prevents someone from doing these kinds of things to a stranger online and there's no defense against it.

First, no I am no a pedophile. I do have an ED, as does every webcomic guy, and they all make similar claims, because it's funny. Steve Jobs also has an ED page that says he throws gay handjob orgies with employees, presumably it's clear that isn't (or wasn't) the case.

Second, I did briefly date a 17 year old when I was 24. Unfortunately I was born in an era where your stupid fuckups can be preserved for all eternity by even one person who hates you (In this case an ex girlfriend, "Calvinandhobbes" in the contributor section of the page).

I was indeed a collossal faggot to think it would work out, but the content of the page is fictional; I did not "take her to Vegas", I met her while living in Florida. Everything witten from my POV on the page was written by Hannah (aka Calvinandhobbes) a girl I had a bad breakup with.

The fallout from that page has made my life pretty difficult. Employers don't know what ED is, it looks like Wikipedia and they're not about to listen to me explain that it's a comedy site, they just sack me and it's on to looking for a new job. Likewise with attempts at dating. I've been single now for 4 years, as the ED page prevents me from holding a lasting relationship. I have struggled with depression, including occasional thoughts of suicide, although I have been attending an excellent therapist that has helped with that.

Since all this began I've done my best not to complain and to simply keep contributing interesting, entertaining content to this site because I know protesting in any way would just make me an even more tempting target. All I want is to share my interest in the ocean and DIY hobby projects with you guys. If I have done anything that you feel makes me deserve all of this I apologize and will do anything within my power to redress your grievances.

When I can afford a small tank of helium and a weather balloon so I can test different designs for weight and stability.

Yes but panels themselves are not reversible in the way that motors and peltier junctions are.

I won't tell you something you can find easily online.

However I can offer a few concepts that may help you understand all similar devices.

Human beings have developed basically only two ways of generating current. The first is by making magnetic things spin inside of a wire loop to drag electrons by their EM field through the loop and thus accelerate them through the circuit. There are also linear generators like the ones used for tidal power that do the same thing but in a straight line.

The other method is a voltaic pile. This is a solid state alternative and while the best known voltaic pile (batteries) are storage, not generation, two other forms are; solar panels and peltier junctions. The first generates electricity from the reaction of photons with the pile and the other generates electricity from a thermal differential. Although a peltier junction is reversible and can create thermal differentials when you run current through it (as you can run current through the first example and it becomes a motor) obviously this isn't true for panels.

It's depressingly crude isn't it? In all this time we have found only two fundamental methods for generating current. Are there more? That's one of those things that keeps me up at night.

Haha! Yeah but it works great. I used that in the Columbia river last Summer, found all kinds of cool stuff down there.

>>4663535

Made my own, gonna use it in a deep lake this Summer.

Here's the map it made.

>>4663522

Workin' on it.

This fully autonomous robot mapped in 3D a 1,000+ foot deep 'blue hole' in Zacaton and returned samples from the bottom.

If we can do this, a successful robotic mission to Europa is definitely feasible.

The Bajau "sea gypsies" live at sea full time. The freedive hunter you saw earlier was a sea gypsy.

We are masters of the sea.

>So when do we merge ourselves with technology and begin breathing underwater?

As soon as we can miniaturize this to implant size and power it off of blood glucose.

Or, we can engineer synthetic blood with the oxygen retaining properties of marine mammal blood. This would extend our breath holding ability to 30 minutes. Add to this a small compressed oxygen canister in the chest cavity to reoxygenate the blood as needed, bypassing the lungs, and you could last considerably longer.

Today, if you have $205, you can just buy this little fella. It's a micro scuba system, gives you 27 breaths and refills in under a minute.

>quick question: will europa even have water? I know that people expext to find a liquid mass inside, but do we have any confirmation that this is actual H20 and not another fluid unable to sustain life?

The ice itself is normal water ice. It'd be more remarkable by far if there were anything but regular water underneath.

Me too. Our future is and must be space faring. But if it makes good sense to farm, mine and settle our own ocean, it will make just as much sense to do the same in the oceans of every planet we settle. It may be our fate as a species to become universally amphibious, especially as by the time we're settling other worlds the difficulty of expanding into their oceans will have dropped to nil.

That defines us as a species. We're the hairless, smooth skinned ape that spends more recreational time in the water than any other mammal. Babies instinctively know how to hold their breath and swim. Oceanic tribes hunt 65 feet down with a speargun. We work our whole lives so that when we retire we can relax on the beach and snorkel in tropical waters. It seems normal but when you look objectively at our fondness for water compared to other mammals it's concpicuous.

That's probably how other intelligent alien species will think of us and what will form the first stereotypes for our species. "Sea monkeys".

Everyone looking for life in space says the same thing; go where the water is. For the bulk of our planet's history the only life was in water. Odds are to find the first extraterrestrial life, we will need an unmanned submersible.

Alien oceans are our great destination. Space travel is just how we get the sub from here to there.

>I think seabros and spacebros can work in harmony and create beautiful science together.

The Challenger Deep is 7 miles down.

Europa's ocean is between 30 and 60 miles down.

Challenger Deep is just the tutorial stage. The true oceans await us in space.
