It's basically the same test, though in recent years I have heard several statements that there is more of a focus on calculus-based questions (previously you could do reasonably well on the exam without solid calculus skills).

Wow, I'm amazed it still works. Small miracles...

Everybody has skills... falling gracefully (or at least in an amusing manner) is a unique one!

An interesting tidbit -- that was filmed at Samsung Austin Semiconductor in Texas right after I left the company to come back to Rochester. The cubicles were our engineering offices, and their surveillance rooms our meeting rooms.

Can't wait to see it implemented in our daily lives!

Another physics item coming up soon... how can you hear a referee's whistle if they are facing away from you?

I'm guessing you're not moving to Hawaii anytime soon?

I'm really loving all the new technology being incorporated into transparent displays, from Gorilla Glass to sapphire screens. Some amazing improvements in scratch resistance and toughness for our smart phones, watches, etc. Great post!

<p>Recently I replied to a post on the College Board’s AP Physics Teacher discussion forum, an act that always seems to be a dicey proposition. A teacher had asked other AP physics teachers for instructional physics video recommendations. I replied with links to one of my favorite video series, the MIT 8.xx introductory calculus-based physics series put together by Prof. Walter Lewin.</p> <p>If you are unaware, Prof. Lewin’s lectures have been immensely popular and have been in many ways the “de facto” standard for online physics lectures. His preparation was well thought out, his content coverage thorough, his demonstrations engaging, and his performances nearly flawless.</p> <p>Recently, however, Dr. Lewin’s lectures have been pulled from the MIT website due to an investigation in which MIT determined that Lewin “had sexually harassed at least one student online.” (<a href="http://tech.mit.edu/V134/N60/walterlewin.html">linkhere</a>). You can still find versions on YouTube.</p> <p>Following my post on the discussion forum, I received several responses from instructors stating that they would not recommend the videos any longer. I briefly responded that the quality of the videos didn’t change, therefore even though Lewin may have been acting in appropriately personally, the videos were not affected and retain their educational value.</p> <p>Several responses were quickly received, ranging from recommendations to use alternate videos to a response stating that posting materials associated with Lewin would be morally irresponsible. Though I do understand the concerns, I think disappointment in the behavior of one of our “physics heroes” is clouding the collective judgment.</p> <p>If referencing the works of scientists who have had personal ethical or moral failings is the “correct response,” we need to recognize how much great work must be thrown away. It doesn’t take long to research the personal lives of Albert Einstein, Richard Feynman, Marie Curie, Edwin Schrodinger, or even Stephen Hawking to find well documented evidence of significant personal life scandals. Why is it that referencing their works in the classroom isn’t morally irresponsible, but referencing Lewin’s is?</p> <p>This same issue surfaces again and again outside just the scientific world. Were Babe Ruth’s accomplishments less amazing (especially in relation to other baseball players of his time) knowing his personal behavior off the field? Were Pete Rose’s 4,192 hits less valuable to his team because he was later found to have a gambling addiction? Should the Cosby Show be banned from syndication due to the show’s star alleged indiscretions? In working toward my teaching certification, my class studied a book by Bill Ayers, whose past actions could easy label him a domestic terrorist. Despite his past, however, as a class we were able to explore and debate the philosophies he promoted in his book in a productive manner. We even re-elected a sitting president who lied under oath AND engaged in significant sexual misconduct. </p> <p>My point isn’t that any of these behaviors are anywhere close to acceptable, nor that we should excuse them. Nothing could be farther from the truth. My point, however, is that pulling Lewin’s videos punishes the many students who could benefit from them. Severing ties with the author, closing the associated discussion forums, and similar actions appear reasonable. Removing the good works done by this individual only makes a bad situation worse. Finally, to say that using the works of a public figure discredited for personal indiscretions is “morally irresponsible,” when looked at in a wider view, just becomes silly. How many library books must you pull from the shelves? How many theories and inventions must be destroyed? And where do you draw the line on what level of personal indiscretion warrants these actions? Is it a felony? A misdemeanor? Last week I received my first traffic ticket for a broken taillight (which was fixed first thing the next morning) — does that invalidate what small contributions I’ve attempted to make to my field?</p> <p>Let’s move back to reality. A beloved and popular teacher allegedly screwed up. Big time. We’re disappointed, and we’re hurt. One of our heroes fell. I get it, and I’m hurt too. But his mistakes don’t invalidate his 40+ years of excellent teaching. Our world is just not that simple.</p> <img src="http://feeds.feedburner.com/~r/PhysicsInFlux/~4/nCqfDO3dmJQ"height="1" width="1" alt=""/> <a href="http://feedproxy.google.com/~r/PhysicsInFlux/~3/nCqfDO3dmJQ/"class='bbc_url' rel='nofollow external'>Source</a>

Thanks for yet another terrific resource for AP Physics 1!

Do you have a favorite coaster?

Great job researching something of interest!

I think you should try some of these trick shots... http://youtu.be/86te7nGLsAA

So, now that we're learning about magnetism... can you explain how a circuit breaker works?

Close... 10 mm is a centimeter, 1000 meters is a kilometer.

I bet the kids love when you come over to watch them!

I can't even begin to imagine how much I use circuits. As a gadget geek, let's see. My digital watch. My computer and mouse. Projector for class, television for daily announcements. Car to drive to school, car radio to listen to fantasy sport updates. Lights, heating, garage door opener, electric razor, hot water heater, coffee maker, refrigerator... and it's not even 8:30 am!

Absolutely... knowing your physics can do wonders for you later in life as a homeowner!

Near the end of the twentieth century scientists learned how to cool a gas of atoms to temperatures billions of times lower than anything else in the universe. </p> <p>Now, in the 21^st century, Einstein’s thinking and ultracold atoms are shaping the development of atomic clocks, the best timekeepers ever made. Such super-accurate clocks are essential to industry, commerce, and science. They are the heart of the Global Positioning System (GPS) that guides cars, airplanes, and hikers to their destinations. </p> <p>Today, the best primary atomic clocks use ultracold atoms, achieve accuracies better than a second in 300 million years, and are getting better all the time. Super-cold atoms, with temperatures that can be below a billionth of a degree above absolute zero, allow tests of some of Einstein’s strangest predictions. <br /> <br />Join Dr. Phillips for be a lively, multimedia presentation—including experimental demonstrations and down-to-earth explanations about some of today’s most exciting science.</h3> <p><br style="color: #606060; font-size: 15px; line-height: 22.5px;" /><span style="color: #606060; line-height: 22.5px; font-size: 14px;">Dr. William D.
