"On the wrong side of history" nghĩa là gì?

'On the wrong side of history' = ở phía sai lầm của lịch sử -> nghĩa là quyết định hoặc hành động chính trị lỗi thời (outdated political decisions or practices).

Ví dụ
Facebook and other social media websites are “in danger of ending up on the wrong side of history” by failing to protect young people.

The Green Party MP whose domestic violence leave legislation was voted in yesterday says National will find itself on the wrong side of history for voting against the bill.

The Daily Mail has stood on the wrong side of history again with a front-page tribute to Donald Trump. The tabloid also claimed people protesting Trump’s UK state visit ‘shame Britain’, and attacked Jeremy Corbyn for standing with them.

Not that Sanders was 100 percent pleased with the Koch brothers. "The insurance companies, the drug companies, Wall Street, and the Koch brothers are devoting a lot of money to lobbying, campaign contributions, and television ads to defeat this proposal," he said. "But they are on the wrong side of history." Somebody should really write a white paper on that argument. ~ Peter Weber.

When a man wants to murder a tiger he calls it sport; when the tiger wants to murder him he calls it ferocity.
~ George Bernard Shaw

Khi một người muốn giết một con hổ, anh ta gọi nó là thể thao; khi con hổ muốn ăn thịt anh ta, anh ta gọi nó là tàn bạo.

dùng điện thôi
spiders can fly, electrostatic (liên quan đến tĩnh điện) energy (năng lượng)!

Spiders have no wings, but they can take to the air nonetheless. They’ll climb to an exposed point, raise their abdomens (bụng dưới) to the sky, extrude (đẩy ra; chế tạo bằng cách đùn chất dẻo (nhựa, kim loại nóng chảy) qua miệng ống) strands (sợi tơ) of silk, and float away. This behavior is called ballooning. It might carry spiders away from predators (động vật ăn thịt, dã thú; người lợi dụng người khác (nhất là về (tài chính) và tình dục) and competitors (đối thủ), or toward new lands with abundant resources. But whatever the reason for it, it’s clearly an effective means of travel. Spiders have been found two-and-a-half miles up in the air, and 1,000 miles out to sea.

...spiders can sense the Earth’s electric field, and use it to launch themselves into the air.

Every day, around 40,000 thunderstorms (bão có sấm sét và thường mưa to) crackle (kêu răng rắc, kêu lốp bốp) around the world, collectively turning Earth’s atmosphere (khí quyển) into a giant electrical circuit (mạch điện khổng lồ). The upper reaches of the atmosphere have a positive charge, and the planet’s surface has a negative one. Even on sunny days with cloudless skies, the air carries a voltage of around 100 volts for every meter above the ground. In foggy or stormy conditions, that gradient might increase to tens of thousands of volts per meter.

Ballooning spiders operate within this planetary electric field. When their silk leaves their bodies, it typically picks up a negative charge. This repels the similar negative charges on the surfaces on which the spiders sit, creating enough force to lift them into the air. And spiders can increase those forces by climbing onto twigs, leaves, or blades of grass. Plants, being earthed, have the same negative charge as the ground that they grow upon, but they protrude into the positively charged air. This creates substantial electric fields between the air around them and the tips of their leaves and branches—and the spiders ballooning from those tips.
