The World’s First Photo of Quantum Entanglement Could Disprove Einstein’s Theory

Albert Einstein was, there’s no other word for it, a genius. The man conceived of special and general relativity, theories that have been breaking brains since the early 1900s. But when it came to the idea that two particles can be entangled, and an effect on one could be instantaneously felt by the other even […]

Map of Computer Science

We built computers to expand our brains. Originally scientists build computers to solve arithmetic, but they turned out to be incredibly useful for many other things as well: running the entire internet, lifelike graphics, artificial brains or simulating the Universe, but amazingly all of it boils down to just flipping zeros and ones. Computers have […]

Bitcoin Q&A: Why “energy consumption” math sucks

[inaudible] [AUDIENCE] Do you think it’s possible to have a blockchain that has the five pillars of a fair currency… while there’s no mining? [ANDREAS] Umm, [one that] has no mining? Possibly. [One that] has no energy consumption? No. People misunderstand the energy consumption of systems like Bitcoin. First, people say it’s a “waste” to […]

Bitcoin Q&A: Mining, energy prices, and fee market

“Is it still profitable to mine bitcoin now that the price has dropped?” This is a common question, but also a common misconception. Even supposedly serious analysts and financial organizations get this wrong all the time. Articles in the Financial Times, Wall Street Journal, and research reports published by JP Morgan Chase, say that it […]

Bitcoin Q&A: Energy consumption

[AUDIENCE] I want to ask you about the energy consumption in mining. [ANDREAS] Yes? [AUDIENCE] What is the solution for it? [ANDREAS] Well, energy consumption in mining is — I think — misrepresented very often in two ways. [Cryptocurrency] mining is one of the few industries that is completely geographically independent, meaning that it doesn’t […]

Bitcoin Q&A: Solar energy & mining in space

[QUESTIONER]: Suppose the solar technology advances very well… [ANDREAS]: Yes. [QUESTIONER]: It will capture a lot of [solar energy] with very high efficiency. So marginal costs will become zero. Then would proof-of-work still work, with marginal costs at zero? [ANDREAS]: That’s a good question. Suppose that solar energy advances with its efficiency and you can […]
