It is with a very heavy heart that we are sharing the news of the passing of Dr. Alfonso (Rick) Radcliffe, who celebrated his 92nd birthday in October. He died    1     (peaceful) at his home     2     the evening of Friday. Rick is survived by his son and daughter-in-law.

Rick was born in St. Louis, 1928. He    3     (accept) in the Physics program at UCLA at 15 years old but delayed     4     (study) to serve in the army. When he was released one year later, Rick returned to UCLA, completing his BS, MS and Doctorate degree.     5     (arm) with a PhD in Control Systems, Rick went to work at Mattel Toys as a Test Engineer,     6     he creatively designed a musical doll. Rick was later hired to serve as Associate Professor of Electrical Engineering for the new minority engineering program at CSUN, becoming the     7    (one) black Dean of Engineering in the entire CSU system. Among his many ground breaking     8     (accomplish), Rick was responsible for hiring     9     (many) women into CSUN’s engineering program than all of the other CSU schools combined. Rick worked at CSUN for 30 years including 10 years of post-retirement project work. In keeping with his investigative mind set, Rick donated his body to UCLA for     10     (science) research.

4 . To figure out if we can die of boredom, we first have to understand what boredom is. For help, I called James Danckert, a psychologist who studies boredom at the University of Waterloo in Canada. “A lot of people think about being bored as being lazy. And it’s absolutely not that,” he says. “Bored people want to be engaged with their world, eager to do something satisfying and exciting. But any attempt to do so is failing.”

That means boredom is usually very upsetting. And it can have physical consequences. In one of his experiments, Danckert made people extremely bored by showing them a video of two people hanging clothes to dry. He found that when people got bored, their hearts beat faster and their levels of a hormone called cortisol (皮质醇) went up, compared to when they watched another video that made them sad. These physical changes were signs that boredom was stressing them out. “It’s not like having a full-on panic attack,”Danckert says. But it’s certainly enough to make boredom unpleasant.

Let’s come back to if boredom can kill you. Back in the 1980s, scientists asked people who worked for the British government a whole bunch of questions, including how bored they felt in their daily lives. The study tracked the participants over time. When any one of them died, the survey recorded the cause of death. In 2010, two researchers matched up these causes of death with the participants’ level of boredom. It turned out that people who said they were more bored were also more likely to have died of heart disease. “We know that prolonged exposure to stress is bad for your health,” Danckert says. A single boring day can’t kill you. But if you’re always bored, the stress could add up into something dangerous.

“Oh no,” you might be thinking. “School is boring, my friends are boring, everything is boring! What’s going to happen to me?” Don’t worry, Danckert says, “As you get older, you get less bored,” mainly because you gain more independence and have to get busy to achieve your long-term goals. And trust me: that’s anything but boring.

A Great Monday

Monday started out well. I woke up on time, ate breakfast and did some last minute studying for my math test later that morning. I was confident of getting good grades. I left my house and ten minutes later, I sat with my friends on the school bus. We were busy chatting about how we spent our weekend. At the next stop, a student named Ryan got on the bus. He was in a rush and tripped (绊倒) over someone’s foot. There was a loud noise as he fell to the floor.

Every one of us on the bus laughed. Ryan got up, brushed his jacket and went to an empty seat. He tried to laugh with us, but his face was red with embarrassment. The rest of the morning went by quickly. I did well in my math test. I read two more chapters of To Kill a Mockingbird in English class. Soon we heard the lunch bell. I met my friends from the cheerleading team in the dining hall. I noticed Ryan a few tables away, sitting by himself. He caught me looking at him. I smiled at him quickly and looked away.

When we finished eating, we went to the courtyard to practice a cheer we would do at that night’s football game. After much practice, we finally managed to do the cheer perfectly. We decided to practice it again one last time. Just like the rest of my day so far, the cheer was going great. I raised my leg for one last toe touch. That was when I felt my jeans (牛仔裤) split (裂开) down the middle of my backside.

I froze. I had no idea what to do. I heard people burst out laughing and I saw them pointing at my torn jeans. I tried to cover myself with my hands, I tried to laugh too, but I felt tears begin to well up in my eyes.

Then I saw Ryan running towards me.

That night, after the cheer at the football game, I found Ryan.

6 . For people, who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today’s sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.

Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can’t let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device (LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.

For those who hunger for some peace and quiet, sound can now create silence. Let’s say you are at the airport, and the little boy on the seat next to you is humming (哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine or point it at the target, and your peace and quiet comes back.

Directed sound is a new technology that allows companies to use sound in much the same way spotlights (聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, “spotsound” creates a circle of sound in on targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.

7 . As is known to us all, the stories we share with one another are significant, which shows our wisdom, providing our inspiration and attaching importance to our development. But occasionally people choose not to tell.

Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

There is a danger in holding back stories that ought to be told. Bobette Buster said it was like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked, their power to destroy is set free.”

There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share, and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

Honesty and openness is important. It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.

Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.
