A Music Video: Janis Joplin’s “Mercedes Benz”

“A song of great social and political import” from the 1960s, as well as a fun song for which to make a music video — or sing, a capella, in public, loudly and obnoxiously. =D

One Possible Definition of Physics

Visual definition of physics

With my metaphorical “mathematics of sets” hat on, this is what physics looks like, to me. The further you go in the field, the more challenging the mathematics gets; also, the better (and more expensive) the toys become.

Calvin and Hobbes, and Election 2016

The current American election cycle was predicted, with amazing accuracy, in the late 20th Century, by Bill Watterson, the creator of Calvin and Hobbes. Evidence will follow. We’ll start with ignorance and apathy, both of which are certainly involved in American elections.

Not wanting to vote and not being allowed to vote are, of course, two different things to Calvin.

While he’s being ignorant and apathetic, Calvin is, at least, honest. Honesty is something which we definitely need, and currently do not have, in American politics, from the left or the right.

If only this fictional duo qualified under the Constitution, we’d be facing this choice, which certainly seems better than the choice we actually have:

Watterson understood, well, the corrupting role of money in politics.

The big issue politicians do not talk about enough is the environment. Why do they not devote more energy to that? Money, of course. The love of money drives people to do harmful and irrational things, and this includes things with obviously-negative environmental impact.

He also created numerous cartoons about pollsters and lobbyists, taking them every bit as seriously as these people deserve to be taken.

America has a lot of single-issue voters. They are not safe from Watterson’s satire. This cartoon is as on-target today as it was when it first appeared.

For what purposes was Calvin willing to do research? Could his spray-painting ambitions include negative campaign ads?

I certainly think so. 

The next cartoon applies equally well, in my opinion, to the words and actions of both Donald Trump and Hillary Clinton.

If the next cartoon doesn’t remind you of the Trump-or-Clinton choice we face, and what an amazing waste of time and energy it is to have to make such an absurd “choice,” please read it again.

Finally, here’s Calvin’s invention of the perfect bipartisan slogan for this campaign season, and its nausea-inducing choice between bad (Clinton) and worse (Trump).

“So what?” Indeed.

Hillary Clinton’s Other E-mail Problem

This has nothing to do with those other e-mails tied to Hillary Clinton — the ones which have recently been under official investigation, and in the news. It’s a completely different thing: e-mails sent out by her campaign for the White House, and unrelated to her time as Secretary of State.

Hillary Needs Me

Other e-mails, entirely too much like this, preceded the “I need you” e-mail I received yesterday. I’ve been making fun of them on Facebook for quite some time, but hadn’t brought them to my blog until now. I’m simply using cropped screenshots from my e-mail account for these pictures, and keeping the e-mail senders, subject lines, and dates together, for each e-mail. If anyone wishes to check the authenticity of these e-mails with the Clinton campaign, that’s fine with me. You’ll find that these e-mails are real (or they’ll lie to you; I can’t rule that out). If lies are told, I’ve got the evidence in my e-mail account, as do many others. This is not a complete set, either; it’s just the most recent of these, um, strange e-mails from her campaign minions. 

Hillary Needs Me 2

I don’t know how I got on Hillary Clinton’s presidential-campaign e-mail list, but I am not complaining about it. If I wasn’t on her campaign’s list, after all, I wouldn’t know that all these e-mails are going out, with her name (and sometimes others, as seen above) as the sender, and such things as “re: last night” in the subject line. That would deprive me of this opportunity to use real campaign materials to ridicule a major-party presidential candidate, or, in other words, prevent this particular bit of fun. There were other such e-mails before June 29 — long before, actually — but this is all of this kind of thing I can stand to put on my blog.

To Hillary Clinton (the person, not her campaign staff): Really, H.C.? Do you not monitor your campaign flunkies at all? These e-mails could bring new meaning to the term “madame president,” and I really don’t think they will help you at the ballot box, either.

To Donald Trump, and his ilk: don’t think this means I support you. I don’t.

For whom will I cast my vote, some may wonder? Well, I have it narrowed down to two candidates, but neither of their names appear in this post. For more information regarding where my vote will go, simply click here.

If You Really Want to Scare Me, Don’t Use Thirteen.

House_Thirteen

I was alerted today, by e-mail, that a blog-proofreading service has found thirteen whole errors on my blog, and they’ll tell me where they are, exactly, if I send them money.

This blog is four years old. It has over 1,300 posts on it, so that’s, um, an average of one error for every 100+ posts. The logical thing to do, I believe, is to keep doing my own proofreading, which I do every time I look at posts, old or new.

I do hope those 13 errors are not disturbing anyone else, though.

Upon re-reading the e-mail, I found three errors. That’s in one e-mail. I’m definitely keeping my money!

George Carlin, on Change

On numerous occasions, I have repeated this experiment, in keeping with the scientific method. I have obtained the same null result as Carlin obtained, each and every time.

Have you noticed what silver’s been doing lately? The price of silver is literally on fire!

silver is literally on fire

Because of the price of silver being literally on fire, they will not be buying and selling troy ounces of metallic silver when the markets open in New York tomorrow morning. Instead, they will be selling “oxide ounces” of silver oxide, in sealed-plastic capsules of this black powder, with an oxide ounce of silver oxide being defined as that amount of silver oxide which contains one troy ounce of silver.

silver oxide capsule

A troy ounce of silver is 31.1 grams of that element, which has a molar mass of 107.868 g/mole. Therefore, a troy ounce of silver contains (31.1 g)(1 mol/107.868 g) = 0.288 moles of silver. An oxide ounce of silver oxide would also contain oxygen, of course, and the formula on the front side of a silver oxide capsule (shown above; information on the back of the capsule gives the number of oxide ounces, which can vary from one capsule to another) is all that is needed to know that the number of moles of oxygen atoms (not molecules) is half the number of moles of silver, or (0.288 mol)/2 = 0.144 moles of oxygen atoms. Oxygen’s non-molecular molar mass is 15.9994 g, so this is (0.144 mol)(15.9994 g/mol) = 2.30 g of oxygen. Add that to the 31.1 g of silver in an oxide ounce of silver oxide, and you have 31.1 g + 2.30 g = 33.4 grams of silver oxide in an oxide ounce of that compound.

In practice, however, silver oxide (a black powder) is much less human-friendly than metallic silver bars, coins, or rounds. As you can easily verify for yourself using Google, silver oxide powder can, and has, caused health problems in humans, especially when inhaled. This is the reason for encapsulation in plastic, and the plastic, for health reasons, must be far more substantial than a mere plastic bag. For encapsulated silver oxide, the new industry standard will be to use exactly 6.6 g of hard plastic per oxide ounce of silver oxide, and this standard will be maintained when they begin manufacturing bars, rounds, and coins of silver oxide powder enclosed in hard plastic. This has created a new unit of measure — the “encapsulated ounce” — which is the total mass of one oxide ounce of silver oxide, plus the hard plastic surrounding it on all sides, for a total of 33.4 g + 6.6 g = 40.0 grams, which will certainly be a convenient number to use, compared to its predecessor-units.

The Spider-to-Human Ratio

spider to human ratio

Since I like spiders, I was pleased to read a rough estimate of 21 quadrillion for the world’s population of spiders (source: here).

The website http://www.worldometers.info/world-population/ gives the current human population as ~7.4 billion. Dividing the estimated spider population by the estimated human population yields Earth’s estimated spider-to-human ratio: 2.8 million.

Yes, your share approaches three million spiders. At least they are good at taking care of themselves!

My Centripetal Force Joke: A True Story

orbit

In the Summer of 2014, with many other science teachers, I took a four-day-long A.P. Physics training session, which was definitely a valuable experience, for me, as a teacher. On the last day of this training, though, in the late afternoon, as the trainer and trainees were winding things up, some of us, including me, started getting a little silly. Physics teachers, of course, have their own version of silly behavior. Here’s what happened.

The trainer: “Let’s see how well you understand the different forces which can serve as centripetal forces, in different situations. When I twirl a ball, on a string, in a horizontal circle, what is the centripetal force?”

The class of trainees, in unison: “Tension!”

Trainer: “In the Bohr model of a hydrogen atom, the force keeping the electron traveling in a circle around the proton is the . . . ?”

Class: “Electromagnetic force!”

Trainer: “What force serves as the centripetal force keeping the Earth in orbit around the Sun?”

Me, loudly, before any of my classmates could answer: “God’s will!”

I was, remember, surrounded by physics teachers. It took the trainer several minutes to restore order, after that.
