One of the most exciting things to happen to knowledge is the increasing amount of free information, available to anyone, for any reason. A recent entry into this new market comes from PhysicsDatabase.com.
There are over 150 titles available for free download, covering a range of science-related topics for students, professionals, and amateurs as well. Here are just three of those selections. Find the entire list here!
How eNotes’ Math and Science intern overcame his trouble with the sciences and learned to love his Biochemistry major.
Science: the subject that many find so difficult to understand (and so boring to even attempt to understand) that they just dread learning about it, dread having to sit in class and listen to the teacher ramble on about atoms and cells and forces of nature. In high school, I used to be the type of student who wanted to ditch my chemistry and biology class. Seriously, who wants to hang around periodic tables and posters of cellular structures all day, and then have to study so hard just to learn on the test that you understood almost nothing? However, when I started college and began studying for my biochemistry degree (being Asian, I was heavily influenced to become a doctor), I began to realize why so many of us perform poorly in and, for some, even fear science. A 3rd year into my studies now, let me share with you my experience of overcoming the negative attitude and eventually growing to love this subject.
“Why do I need to learn this? When am I ever going to use this information in my lifetime?” These are questions that we’ve all asked at some point in our scientific studies. In fact, the professor of my public speaking course raised this question just 2 days ago, referring to the sciences. This is one of the many reasons that science classes may seem so difficult and scary. It seems so arbitrary and foreign to us, like learning a whole new language that we will never use, and school fails in making it seem less frightening, in making it more familiar. Instead, we are driven away by how test-oriented the material is and the amount of memorization that is required.
My love for the sciences began in my first physics and chemistry courses. We were learning about exothermic (release of heat) chemical reactions and kinetic energy. Sure, I understand that when favorable chemical reactions naturally occur spontaneously go towards products and release energy as heat, but what does this mean and why do I care? Out of frustration in how poorly I was doing in the class, I decided to approach learning science through another method. I began to explore where these concepts occur in my everyday world and that’s when I stumbled across explosions. Those beautiful explosions seen in fireworks and those awesomely crazy explosions seen in action movies can all be fundamentally explained by the basic concept of exothermic reactions. All that force, heat/light, and fire that we see as a result of an explosion is all due to a chemical reaction that releases a lot of heat, causing the rapid expansion of air molecules. How cool is that?! All that insanity due simply to a sudden, quick expansion of air molecules that help transfer heat! I’d never thought something so simple can be responsible for what we see in fireworks and explosions. This is when I realized that I can make science a lot easier and a lot more interesting to understand.
Over the last few years, I stumbled across more interesting applications of the concepts I was learning in class. In quantum mechanics, I learned that teleportation is possible and that scientists have already teleported incredibly small particles from one island to another (shout out to all those Star Trek fans who fantasize about traveling from one place to another in a matter of seconds). In physics and chemistry, I discovered the most efficient way to drive a car, meaning I can now consistently get above 40 miles per gallon in my 1996 Honda Civic, which is incredible considering that a lot of fuel efficient cars these days average about only 32 miles per gallon.
The main point I’m trying to get at is learn how the science can be applied and try to relate it to a phenomenon that you find fascinating, especially if you are someone who is currently struggling in your science courses as I did (my GPA actually dropped below a 3.0 when I started college). Explore the internet and answer that question your little voice keeps asking in your head, “When am I ever going to use this?” It’s what led me to finding better and easier ways to perform simple tasks, such as driving, cooking, and fixing broken appliances. Although it may be true that science comes more naturally for those who are left brain dominant, all you need to do is be creative and find some way to connect that scientific concept to something that really interests you, and you don’t need to be an Einstein to make that happen. In fact, that’s how most of us learn in other subjects, but science just seems so foreign at first that it’s hard to take that first, eye-opening step. Once you take that step, though, you’ll begin to realize all beautiful ideas and revolutionary technology arise from surprisingly simple concepts with a bit of imagination and experimentation. It’s what allows for the possibility of teleportation, the possibility of substituting electricity with quantum particles to make computing millions of times faster, the possibility of finding cures for life-threatening diseases, and the possibility of traveling through space and time. That’s pretty awesome if you ask me.
So, as Jesse Pinkman expresses it in Breaking Bad, “Yeah, science!”
I don’t know about you, but when I go to bed at night, my brain goes into Super Worry Overdrive. I worry about my bills, my kids, my first drafts (like Anne Lamott, I am afraid someone will find my unedited work and will assume I have committed suicide when I realized my talent was gone).
One of my favorite Tumblr’s, This Isn’t Happiness, recently posted a list of things very intelligent people worry about. Spoiler Alert: Whether they can continue to continue paying for HBO is not on the list. I had to look up some of the things they worry about. Suddenly, whether my cats need therapy or not (they do) is not as pressing. Apparently, I, and you, have more troubling things to keep us on edge:
- The proliferation of Chinese eugenics. – Geoffrey Miller, evolutionary psychologist.
- Black swan events, and the fact that we continue to rely on models that have been proven fraudulent. – Nassem Nicholas Taleb
- That we will be unable to defeat viruses by learning to push them beyond the error catastrophe threshold. – William McEwan, molecular biology researcher
- That pseudoscience will gain ground. – Helena Cronin, author, philospher
- That the age of accelerating technology will overwhelm us with opportunities to be worried. – Dan Sperber, social and cognitive scientist
- Genuine apocalyptic events. The growing number of low-probability events that could lead to the total devastation of human society. – Martin Rees, former president of the Royal Society
- The decline in science coverage in newspapers. – Barbara Strauch, New York Times science editor
- Exploding stars, the eventual collapse of the Sun, and the problems with the human id that prevent us from dealing with them. — John Tooby, founder of the field of evolutionary psychology
- That the internet is ruining writing. – David Gelernter, Yale computer scientist
- That smart people—like those who contribute to Edge—won’t do politics. –Brian Eno, musician
- That there will be another supernova-like financial disaster. –Seth Lloyd, professor of Quantum Mechanical Engineering at MIT
- That search engines will become arbiters of truth. —W. Daniel Hillis,
