If you’re in your 20s or even 30s, you might feel a lot of uncertainty all the time. You may be not sure what your life purpose is.1.This is normal.

We all want to have a certain life purpose. We all want to feel we’re on the right path. We all want to perfect our habits, our routines, or our productivity. We all want to feel more certain, and perfect in what we’re doing.

There is a struggle between the comfort of certainty and perfection and the fear of uncertainty and being suboptimal(不最理想的).

Let me let you in on a secret: no one is free from this struggle. Look at the most successful people you can think of —Bill Gates, Obama, Taylor Swift. 2.Do you think they have certainty and a feeling of reaching perfection? Not a chance. There is not one of us alive, not me or anyone else, who ever feels certainty about their purpose or path. If they do, they’re fooling themselves. 3.

No one ever feels they’ve found the perfect productivity routine, the perfect version of themselves. 4.

We all feel uncertainty, all day, and we all struggle with it. Some people have grown more comfortable with it than others, but in general no one likes uncertainty.

5.That’s perfectly OK, perfectly normal. Don’t run from it. Instead, stay with this uncomfortable, unappealing uncertainty. It’s here in you, a part of this moment, a part of you but not the whole of you.

A.Because it doesn’t exist.

B.Do you think they have it all figured out?

C.This uncertainty you’re feeling is unpleasant.

D.But if they’re honest, they don’t feel that certainty.

E.See if you can tell what you’re being uncertain about.

F.So focus on what you actually have right in front of you.

G.You may be uncertain about what path you should take in life.

At one time or another in your life you have probably done origami, even if it was just making a paper airplane or something more complicated like a paper crane. The chances are that as you did it, you reflected on how inventive this traditional art is. Animals, boxes, flowers, boats: it all can be created from a single square or rectangular sheet of paper simply by folding it. No cutting, no pasting.

But did you ever stop to think how the same techniques might be applied to engineering? Equipment that could be of real practical use? Origami meets the demand for things that need to be small when transported and large when they arrive, like the everyday umbrella. In fact, origami-inspired creations have already flown in space; in 1995, Japanese engineers launched a satellite with solar panels that folded like a map.

“It’s now mathematically proven that you can pretty much fold anything,” says physicist Robert J. Lang, who quit his engineering job eight years ago to fold things full time. Lang, an origami enthusiast since age six, advised a advised well-known ear manufacturer the best way to fold an airbag into a dashboard. He is currently working on a space telescope lens that, if all goes according to plan, should be able to unfold to the size of a football field.

At the other end of the scale, researchers are also working on tiny folding devices that could lead to breakthroughs in medicine and computing. There’s no doubt that computers of the future may contain tiny, folded motors or capacitors for faster processing and better memory.

Applications for origami engineering go further than many of us might imagine. “Some day,” says MIT’s Erik Demaine, “we’ll build reconfigurable (可重构的) robots that can fold on their own from one thing into another, like Transformers. Too much like science fiction to be true? Maybe—though you certainly wouldn’t want to bet against it.”

1.What do we know about origami?

A.It consumes lots of time. B.It involves interesting ideas.

C.It requires complex techniques. D.It has to do with cutting and pasting.

2.Which of the following is an application of origami?

A.A space telescope lens can be folded to the size of an umbrella.

B.A satellite is equipped with solar panels and a folded map.

C.An airbag can be better folded into a dashboard of a car.

D.A future computer contains many huge folded motors.

3.What is Erik Demaine’s attitude towards origami engineering?

A.Hopeful B.Doubtful.

C.Disapproving. D.Ambiguous.

4.In which section of a newspaper may this text appear?

A.Entertainment. B.Culture.

C.Education. D.Pop-science.
