If there’s one thing I’ve realized since becoming a male college student, it’s that finding a summer job is nearly impossible. I’ve applied to so many places and I’ve experienced so many interviews, but I always either get straight-up refusal or never hear from the company again.

One time, I even called one of the companies multiple times, but the manager avoided me. I was close to giving up. I felt like I was the only one struggling hard. I had a pretty good resume, and I always dressed nicely for my interviews, so why couldn’t I get a job?

Well, the reason is actually right in front of me—I am a student. Companies generally want students who can work all year long, but most of them aren’t willing to be flexible with schedules. I couldn’t tell you how many times interviewers told me that they were looking for someone permanent.

I tried looking for jobs marked as temporary ones. And I even once tried to apply through a temporary agency. But it didn’t work. Even if I wanted to work during the school year, none of the companies wanted to hire me because of my limited weekday availability. And despite not knowing if I could juggle (尽量兼顾) both school and a job, I even started to tell interviewers that I would like to work during the school year and give up my weekends. But I had no luck.

I’m not sure if there are others like me out there. But if you are going through something similar, what I want to tell you is to keep on trying. Despite being rejected so many times, I still applied for any job that I was qualified for. I even started my job search before the semester ended to get ahead. Eventually, I got my ideal summer job.

I know it’s frustrating, and you may feel like you’ve tried everything—that’s how I’ve felt for a long time. And now, with companies requiring years of experience, it’s even harder to get a job if you’re someone like me. But don’t give up. Keep searching and applying, sign up for sites that send you job offers and look on the university’s website for on-campus jobs.

A team of physicists at the University of Edinburgh, working with an infection and immunity specialist, has, via experimentation, validated a theory to explain why paint dries at the same rate regardless of humidity (湿度) levels.     

Generally, paint should dry faster on an outdoor fence on a dry day than when it is humid because evaporation (蒸发) occurs faster when the air around a liquid source is drier. But evidence suggests this is not the case for paint and some other liquids. Chemist Salmon and his colleagues developed a theory to explain why. They suggested it is because large molecules in the liquid are pulled to the surface during evaporation, forming a “polarization layer” that prevents evaporation, and by extension, drying. In this new effort, the research team worked to test this theory.

The researchers drilled five holes into a short cylinder (圆柱体) and inserted glass tubes in a horizontal position — each was then sealed in place. They then added a quantity of PVA, a kind of chemical substance, into the cylinder, which they placed on a scale. They poured a thin layer of oil on top of the liquid to prevent surface evaporation. The final touch involved placing an air flow box over the top of the cylinder to allow for controlling humidity levels. The team then ran multiple 17-hour trials to determine evaporation rates, using the scale to measure how much liquid evaporated from the tubes at different humidity levels, ranging from 25% to 90%.

The researchers found that as expected, evaporation rates remained constant for approximately three hours. But then, rates plummeted, as was theorized by Salmon, regardless of humidity levels. The evaporation rate didn’t decrease as humidity increased during the initial three hours. However, the theory only appeared to hold for humidity levels up to 80% — at rates higher than that, evaporation did slow down, which the team suggested was likely due to some other forces.

The researchers suggested their work could have medical applications as recent research efforts have shown that respiratory droplets (呼吸道飞沫) tend to form skins similar to those seen in the experimental equipment.

What a comedian can teach you about managing stress

We often accept stress as part of the cost of modern life, but it really doesn’t have to be. We all know that laughter is the best medicine.     1     People who can laugh at their own misfortunes bounce back faster and stronger. Here is what a comedian says about coping with stress.

You can try to find a different perspective.     2     Once a friend of mine fell asleep in the middle of a class. His teacher decided to make fun of him by inviting students to applaud, wondering whether my friend would applaud along when he woke up. He did and the whole class burst outlaughing. After learning everything, he was both embarrassed and ashamed of course but after a while, my friend laughed. “If this had happened to someone else, it would have been amusing. So it’s no less funny, just because it happened to me. “

    3     There’s no doubt that we all experience great stress now and then. We’ve all been personally affected, in some way. You might not have felt like laughing at the time But now, looking back, you could consider all of the strange aspects of the experience and all of the things you did to keep active or simply stay sane (神志正常的) .

When you share stories with your friends, you can choose to share stories of trauma (创伤) and pain, or you can choose to lift their spirits with stories of hope and growth.     4     Take the exact same story and change the focus from “feel sorry for me” to “laugh with me”. Keep in mind that we’re all in this together, that we all share the same ridiculous experiences, and that we can laugh together at whatever life throws at us.     5    

In late 2021, I began to have a little bit of a midlife crisis. When my father was 48 years old, he had a heart attack that nearly ended his life. As I _________ my mid-forties, I knew that I needed to make a change in my life. I wanted to do something _________ to prove to myself and everyone else around me that I wasn’t going to have the same fate.

As I was trying to determine what kind of _________ that I wanted to set, I found a _________ called The Rut. The Rut is a series of races that are _________ in Big Sky, Montana every September. There’s multiple distances, but the 28 Kilometer _________ is the most popular, as well as the most _________ of the entire series. This race is regularly listed in the top ten most difficult races in the world. It involves almost 8,000 feet of elevation (海拔)_________ . This was the type of race I was _________ .

I also did a detailed training __________ . Even if I was traveling for business, I would stick to it and never __________ a workout (训练). And then came race day.

That day, Big Sky Montana, was unseasonably __________ , almost 100 degrees Fahrenheit. The race is going almost entirely above tree line, which means that you just are __________ to the elements (恶劣天气) nearly the entire time. Many people __________ out of the race halfway. But I finished it. When I reached the finish line, I was greeted by my wife and children, also friends that had traveled with us to Big Sky that day. This was the biggest challenge I had made for myself, but I __________ it.
