The decisions that we make shape us throughout our lives. No matter what decisions we make, good or bad, each one puts us on a new road in the future. Make a bad decision? No problem. Learn from the decision and make another decision to get on a different path. This is advice that I got from Tony Robbins in his book Awaken the Giant Within. This is a book that I recommend(推荐) to anyone wanting to develop a fire to make changes in their life. It helped me to understand how fear of making poor choices was hindering me from becoming the great man who I am today. Now I am not saying I am a well-known person in any particular circle. But I am the king of my castle working hard and trying to make good decisions in regard to the paths that I have chosen. I am a great man in the eyes of my wife and my children. And that is all the recognition that I need in my lifetime. And I know that my past failures have been the building block that I continue to use to build my career and self-image in my community that I live in.

    Ben Lerer, cofounder of the CEO of Thrillist Media Group, is a good example of this. In an article on the Fast Company website, Lerer talks about this very subject. He says, “I've had to make some really tough decisions but finally, I think the best companies are those that can recognize when something isn't going right, and fix it, instead of just turning a blind eye because it's easier.” Great people make decisions. When a decision does not have the desired result, make a different decision. It does not get any simpler than that.

    Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, "Mum, I can't peel (去皮)potatoes. I have only one hand. "

    Mum never looked up from sewing. "You get yourself into that kitchen and peel those potatoes," she told me. "And don't ever use that as an excuse for anything again!"

    In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.

    That night I told Mum about it. She hugged me, and I saw her determined look. The next afternoon, she took me back to school. At the deserted playground, Mum looked carefully at the bars.

    "Now, pull up with your right arm," she advised. She stood by as I struggled to lift myself with my right hand until I could get the bar with my other elbow (月寸）.Day after day we practiced, and she praised me for every rung (梯级）I reached.

    I'll never forget the next time, crossing the rungs； I looked down at the kids who were standing with their mouths open.

    One night, after a dance at my new junior high, I lay in bed crying. I could hear Mum came into my room. "Mum," I said, weeping, "None of the boys would dance with me."

    For a long time, I didn't hear anything. Then she said, "Oh, honey, someday you'll be beating those boys off with a bat." Her voice was slight and cracking. I looked out from my covers to see tears running down her cheeks.

    Then I knew how much she suffered on my behalf. She had never let me see her tears.

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have-in just two years-nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable (商业可行性) generation of solar fuels that could replace coal, oil, and other fossil fuels.

Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and carbon dioxide. Researchers are exploring a range of possible target fuels, but one possibility is to produce hydrogen by splitting water.

Each water molecule (分子) consists of one oxygen atom and two hydrogen atoms. The hydrogen atoms are extracted, and then can be reunited to create highly flammable hydrogen gas or combined with CO 2 to create hydrocarbon fuels, creating a plentiful and renewable energy source. The problem, however, is that water molecules do not simply break down when sunlight shines on them-if they did, the oceans would not cover most of the planet. They need a little help from a solar-powered catalyst (催化剂).

To create practical solar fuels, scientists have been trying to develop low-cost and efficient materials that perform the necessary chemistry using only visible light as an energy source.

A new method was developed through a partnership between the Joint Center for Artificial Photosynthesis (JCAP) and Berkeley Lab's Materials Project, using resources at the Molecular Foundry and the National Energy Research Scientific Computing Center (NERSCC). JCAP focused on developing a cost-effective method of turning sunlight, water, and carbon dioxide into fuel. It is led by Caltech with Berkeley Lab as a major partner. The Materials Project is a program based at Berkeley Lab that aims to remove the guesswork from materials design in a variety of applications.

"What is particularly significant about this study, which combines experiment and theory, is that in addition to identifying several new compounds for solar fuel applications, we can also learn something new about the basic electronic structure of the materials themselves." says Neaton, the director of the Molecular Foundry.

A seismic (地震的；重大的) shift in climate science might be heating up.

New research shows that sound waves, produced by earthquakes can be used to measure temperatures in the ocean which traps 90% of the heat Earth absorbs from the sun，making long-term changes in ocean warmth, a major factor in how the world might respond to global warming.

For years the main approach of measuring ocean temperature has been Argo, an array (阵列) of 4000 automatic floats, which drifts the globe, sampling ocean water and measuring its temperature. Yet Argo measurements stop at 2000 meters.

The new technique called "Seismic Ocean Thermometry", would be especially useful in detecting long-term changes in ocean temperatures deeper than Argo's reach.

"Ocean Acoustic Tomography", the basis for the current research, was first tested nearly 30 years ago. The initial studies created sound waves artificially, basically increasing the volume on giant underwater speakers. Scientists measured the sound's travel time from the speakers to receivers thousands of kilometers away. Because ocean temperatures affect the speed of the waves, the researchers could calculate average temperatures along their paths. But some believed the noise was a threat to ocean life and the technique never took off.

The new study instead uses a natural sound source for investigation: earthquakes making a low, continuous noise beneath the seafloor off the coast of Sumatra that drum up sound waves in the ocean. On the shores of the Chagos Islands in the East Indian Ocean, between 2005 and 2016 Seismic Station Diego Garcia recorded seismic waves produced by those earthquakes. Some of those waves created physical changes in land and sea as they traveled. Others were sound waves or T waves that moved through the deep ocean, delivering valuable data about ocean temperature.

12 years of data coupled with mathematical models pointed to a temperature change of roughly 0.044 degrees per decade, a trend larger than those predicted by Argo. The findings suggest that Seismic Ocean Thermometry is a feasible method to measure changes in ocean temperature. Further data from other regions of the globe and other timeframes would help improve the warning models and predictions.

And in future studies the researchers plan to listen directly for sound waves, using a network of hydrophones, microphones which detect sound waves under water. Sound waves set the tone for a deep dive into our warming oceans even if they fail to reach 60000 miles under the sea?
