Anti-matter is produced at CERN for study https://home.cern/topics/antimatter . The problem is not production of it but the economy of producing it. It's still very costly to produce and then to build and engine ar

I would rather classify that as "unfortunate". Yes there are obviously biological harms in radiation exposure but that is what science & engineering is for. We know the power of nuclear energy so in order to harvest it, the ri

Exactly - i think there should be more companies & organizations working towards pushing this. To become space-faring, we need to get from 1ev per bond of molecule level of energies obtained from chemical to 1GeV levels atleast!

Well chemical rockets are at a stage where all it needs is scaling up to get more power. But I do agree with you, the complexity and sizes needed makes you wonder why waste so much effort on some technology which has inherent physical limit

What do you guys think of Laser sails & laser-based propulsion methods? The science exists now, seems like its only an engineering challenge. Phil Lubin has a paper on it as well https://www.nasa.gov/sites/default&#

wow - the views of the Western Sahara, Namibia, Kenya, Zanzibar & the water driven mill is simply staggering! I wonder what were his costs overall. That truck surely looked like a petrol/diesel gargling machine!

It's very interesting and odd that a few months ago such an elite group came together to announce this trip and then now a new paper has announced finding of a habitable planet around the sister star system? I sound like a conspiracy n

My German friends had suggested that I read "Mein Weltbild" as it contains a lot of the worldview of Einstein. I tried to look up the English edition for it (now published by a major American publishing house) and it seems like a

i think its more of a thing that happened in retrospect. Tesla was not started by him and neither was Solar City. And SpaceX only came about because we wanted to see how we can grow plants on Mars. So even his vision of Mars as a contingenc

I wonder if they combine these two with SpaceX - Elon Musk might well become the first trillionaire.

Thanks for the suggestion. Tried Clarifai's demo - their API & Pricing is nice as you said but they just don't have much to offer in terms of labels and feature detection when you compare to what Microsoft's or Google&#x2

ok - my bad. I just saw the AlchemyVision has been merged into Visual Recognition starting May 20th. We will definitely check it out to see what extra features have been added. qq - Is the API stabalized, by which I mean will there be furth

So I tried Microsoft's CV & IBM's AlchemyVision on the same image (since they both have an online demo sandbox). The Microsoft just gave me back more labels and stronger sentiment figures for same labels. Hence narrowed it dow

Found 2 good lecture notes by t'Hooft & Sean Carroll which talk about tensors in relationship with GR http://www.staff.science.uu.nl/~gadda001/goodtheorist/gr.htm...

I tried polymail(no imap support for months), Airmail (no link tracking or read tracking,oddly slows my mac,lot of small bugs, UI felt sluggish), apple mail(haha - next one), outlook (too skeumorphic on mac + too heavy + no swipe gestures)

Ask HN: Can someone teach me tensors?

I am a first time buyer and spent months comparing scopes, talking to people who owned my top choices, etc. Finally settled on Celestron Astromaster 140EQ. It is just fantastic to setup and quickly get seeing - an important factor for first

Can't you use Google Save to do something similar? What are the benefits on top of that?
