为什么我们要关注经济学

By •

Amanda was three years old and had no interest in learning to use the bathroom. Her father, Steven Levitt, decided to try something new. He told his daughter, “Amanda, every time you go pee pee in the potty, I’m going to give you M&Ms. Okay?” Amanda loved M&Ms. At first, the plan seemed to be working perfectly. Amanda started going to the bathroom to pee. Levitt was very pleased with himself. But just a few days later, things changed. A few minutes after Amanda went to the bathroom, she said she had to go again! Every few minutes, she wanted to try to pee – just so she could get her candy reward. This wasn’t what Levitt had in mind at all.

人类观测星系的历程

By •

People have always looked into the sky and tried to explain what they saw. Some early civilizations created fantastic stories to explain the patterns above us. Our modern scientific understanding shows the truth is more extraordinary than any of these tales. Some small dots of light in the sky are actually enormous objects called galaxies, made up of billions of stars, some so far away that it took billions of years for the light to reach us. These galaxies are shaped, not by the exploits of gods, but by a whole range of incredible objects, like black holes in space from which nothing can ever escape.

2050年，我们将用什么来替代化石能源？

By •

Welcome to the year 2050. In cities around the world, cars whiz past tall buildings and factories, yet the air is clear, clean, and cool. People have stopped burning coal, oil, and gas to run engines or make heat and electricity. These fossil fuels no longer spew pollution and greenhouse gases into the air. As a result, climate change is slowing. Dangerous wildfires, hurricanes, and other natural disasters are becoming less common. Humanity has managed to back the world away from the brink of disaster.

In the Star Wars movies, the droid R2-D2 carries messages, puts out fires, and while trapped on Jabba the Hutt’s sail barge, even carries a tray of drinks. R2-D2 also saves the heroes’ lives on several occasions . C-3PO and R2-D2 are both servants and friends. The idea that people might create machines to do tasks for them has been around for centuries— but only in myths and science fictions. Golems, animated clay statues, march through Jewish folklore. And Greek myths describe living metal statues called Automata.

药物之旅：药理学的奥秘

By •

You wake up and open your eyes, your head is pounding. Maybe a little breakfast will help. You try a few bites of an egg on toast, but your head hurts too much to eat. Maybe you’re getting sick? With a groan, you walk to the medicine cabinet. You find a bottle of Tylenol. (The technical name of this medicine is acetaminophen). You pop a pill in your mouth, take a gulp of water and swallow. Then you lie down and wait. As the medicine starts to work, your headache will go away.

面对建筑、体验建筑——像建筑师那样思考

By •

As a small child, did you build forts out of branches or snow? Or use the building block to create your first architectural work? If you did, you had to think like an architect. An architect is someone who transforms space with buildings, gardens, and other structures . But they don’t do this merely for practical purposes . Architects are artists. Instead of paint or clay, they work with structures and spaces to express important ideas or evoke human emotion. Architects are also scientists and engineers who study the world and find ways to solve problems and create order. Architects might even question existing ways of thinking to move civilization forward.
