single goal, to face the common challenge for us all.” The physicist shared more ideas to motivate the younger generation to continue exploring space. Hawking stated, “a new and ambitious space program would excite (young people), and stimulate interest in other areas, such as astrophysics and cosmology.”
Hawking also revealed his vision for other forms of energy that could move us to a new planet. He warned the audience, “The Earth is under threat from so many areas that it is difficult for me to be positive.” He continued, “Our natural resources are being drained, at an alarming rate. We have given our planet the disastrous gifts of climate change, rising temperatures, reduction of the polar ice caps, deforestation, and decimation (大量毁灭) of animal species. We can be ignorant, unthinking lot (人).”
The professor warned the audience that doing nothing would lead nowhere. He said, “If we
succeed we will send a probe ( 航天探测器) to Alpha Centauri within the lifetime of some of you alive today. It is clear we are entering a new space age. We are standing at the threshold ( 起点 ) of a new era. Human colonization and moving to other planets is no longer science fiction, and it can be science fact.” Hawking advised the audience to move to other worlds because we are running out of space.

Smartphones are our constant companions. For many of
us, their glowing screens are a ubiquitous (十分普遍的) presence, drawing us in with endless distractions. They are in our hands as soon as we wake, and command our attention until the final moments before we fall asleep. Steve Jobs would not approve.
In 2007, Jobs took the stage and introduced the world to
the iPhone. If you watch the full speech, you will be surprised by how he imagined our relationship should be with this iconic invention. This vision is so different from the way most of us use these devices now. In his remarks, Jobs spent an extended amount of time demonstrating how the device utilized (应用) the touch screen before detailing the many ways Apple engineers had improved the age-old process of making phone calls. It’s the best iPod we’ve ever made,” Jobs exclaimed at one point. “The killer app is making calls,” he later added. Both lines drew thunderous applause.
The presentation confirms that Jobs imagined a simpler iPhone experience than the one we actually have more than a decade later. For example, there was no App Store when the iPhone was first introduced, and this was by design. Jobs was convinced that the phone’s carefully-designed native features were enough. He did not seek to

completely change the rhythm of users’ daily lives. He simply wanted to take experiences we had already found important－listening to music, placing calls, generating directions－and make them better.
The minimalist (简约主义者) vision for the iPhone Jobs offered in 2007 is unrecognizable today－and that is a shame.
Under what I call the “constant companion model,” we now see our smartphones as always-on portals (通道) to information. We have become so used to it over the past decade that it is easy to forget the novelty (新奇之处) of the device. It seems increasingly clear to me that Jobs probably got it right from the very beginning: Many of us would be better-off returning to his original minimalist vision for our phones. Practically speaking, to be a minimalist smartphone user means only using your device for a small number of features that do things of value to you. Otherwise, you simply put it away
