Sir Humphry Davy, a British chemist who was born in 1778, likes dangerous experiments.

He was fired when he was a pharmacist because of the explosion.

Later, as a chemist, he liked to inhale the gases he produced at work.

He also found that nitrous oxide (laughing gas) was a powerful drug.

"Unfortunately," Oxford University Press, Oxford University Press) about the life of Sir David wrote, "the same habits cause there are a lot of time he almost killed himself, often poisoning let in the last 20 years was a patient in his life."

The cost is likely to be worth it: David isolated substances such as calcium and strontium, discovered iodine, and produced the first electric light.

Much like David, Britain is now experimenting with itself for the benefit of humanity.

Few developed societies are as reckless as this, which is why the Brexit experiment seems so precious.

In the process of poisoning itself many times, brexit continues to be a surprise to both the brexiters and the remain.

Here are some initial lessons for other countries:

When a problem of inevitable differentiation becomes the focus of attention, society splits.

The brexit vote has triggered unprecedented resentment in a country that has traditionally been less concerned about politics.

Insulting languages such as "the enemy of the people", "saboteurs", "racists" and "where to go" have become the everyday language of the British.

Arguments over leaving the European Union have divided several generations between family weddings and Christmas.

All of this is to avoid: until the referendum before, there are very few British people view of the European Union (EU) be strong, as few americans think about transgender toilet, until they found the problem of politicians.

If you have to deal with this kind of argument, it's best to try to find a compromise, rather than a winner-take-all solution, such as a referendum.

All countries need real-time election regulators.

People have always won votes by lying.

But now they have social media.

So, all the slow, understaffed and 20th-century electoral regulators who retain the way of doing things in the 20th century must re-establish themselves as judges who can tell the truth immediately.

Not long ago, the national bureau of Statistics (the UK Statistics Authority) thus condemned Boris Johnson (Boris Johnson), because he repeated champions will make off the British national health service (NHS) save 350 million pounds a week cost of nonsense.
