What blockchain does is shift some of the trust in people and institutions to trust in technology. You need to trust the cryptography, the protocols, the software, the computers and the network. And you need to trust them absolutely, because they're often single points of failure.
When that trust turns out to be misplaced, there is no recourse. If your bitcoin exchange gets hacked, you lose all of your money. If your bitcoin wallet gets hacked, you lose all of your money. If you forget your login credentials, you lose all of your money. If there's a bug in the code of your smart contract, you lose all of your money. If someone successfully hacks the blockchain security, you lose all of your money. In many ways, trusting technology is harder than trusting people. Would you rather trust a human legal system or the details of some computer code you don't have the expertise to audit?

Some scientists fear we are nearing a point of no return in the Amazon rainforest, which exerts power over the carbon cycle like no other terrestrial ecosystem on Earth. Evidence is mounting that in certain areas, localized iterations of irreversible damage may already be happening.

Sometimes I get asked "have you ever seen someone do XYZ to acquire customers?" Turns out, the highest vote of confidence I can give is, "No I haven't, and that's good -- that means there's a higher chance of it working. You should try it."

America is in a dark place. There are no simple ways forward or easy solutions that could bring people together.
In this post, I'll try to explain how simple rules for electric and magnetic fields demonstrate that all velocities must be less than the speed of light. It can be done by imagining the consequences of a simple experiment, where a charged particle is watched by two different observers.

The problem with this alluring image is not just that it is false. The myth of Nazi occultism is more than an amusing curiosity, a testament to the power of cinematic suggestion. It actively detracts from a historical understanding of the very themes it highlights. It yields a distorted view of Nazism and a distorted view of occultism. But it also offers an occasion for critical reflection, a chance to see how we might make better sense of the tangled history of occultism in the Nazi era. It might even help us to understand Nazi evil and the not-so-hidden forces behind it.

"There are some tragic cases of children whose brains failed to develop because of their parents being ill-informed vegans," says David Benton, who studies the link between our diets and brain chemistry at Swansea University. In one example, the child was unable to sit or smile. In another, they slipped into a coma.
Later in life, the amount of B12 in a person's blood has been directly correlated with their IQ. In the elderly, one study found that the brains of those with lower B12 were six times more likely to be shrinking.
Even so, low B12 is widespread in vegans. One British study found that half of the vegans in their sample were deficient. In some parts of India, the problem is endemic — possibly as a consequence of the popularity of meat-free diets.

With COVID-19, vaccines still fulfill their primary role: protecting against severe disease. According to the US Centers for Disease Control and Prevention, vaccinated people who catch the Delta variant are 25 times less likely to have a severe case or die. The overwhelming majority who do catch it will have mild or no symptoms.
But growing evidence suggests that, with the Delta variant, fully vaccinated people can still transmit the virus.
