The Geek usually does not write about history, but he will make an exception.  First, Easter this year coincides with my father’s birthday.  He was born on this date in 1919.  If he were still alive, he would have just turned 91 years old.  My granddad on his side lived to that age.

Second, Easter is by proclamation the highest of the Holy Days in the Christian tradition.  Christmas is also joyful, but everyone is borne and only One has, as tradition and religion insists, been resurrected.

Third, the Fulbright College of Arts and Sciences insisted on a well rounded education before anyone could be graduated.  Whilst I am a scientist, I appreciate literature, art, architecture, and especially history.

On a historical note, today is the date on which Martin Luther King was assassinated in 1968.  On a more personal historical note, my father would have been 91 today, but he died in 2005.

There was no Pique the Geek last week because I was preparing for Youngest Son to visit.  We had a great time last week, cooking, eating, throwing darts, and rebonding.  For those of you interested in what we ate, I hosted What’s for Dinner last evening, here.

It is not either possible nor feasible to attempt the fusion that Sol does here on earth because of the impossibility of gathering enough mass to make a very slow reaction work (remember, fusing two protons to a deuteron requires the involvement of the weak nuclear force, and that is a very slow process), nor the temperatures required to make that happen.

Please see the two previous installments of this series here and here, to make things more clear.

Youngest Son came to visit this week (the reason why there was no Pique the Geek last Sunday, getting ready for his visit).  He is 20 and is in culinary school.  I am actually sort of pleased, as cooking good food is as important as being a scientist, and actually involves a lot of science to do it well.

We had a great time!  After the 10+ hour drive, he was pretty tired, but hungry.  I made Frog Sandwiches for both of us late Monday night (recipe available on request), talked, joked, went meet my dear neighbors across the street, and threw some darts.  Neither of us were very good at darts Monday.

There are always times when things won’t be what we wish, and the Fine Structure Constant is no exception to this rule. We humans usually see what we believe rather than what is, and to that end, it comes straight from nature’s gag reel.

There is a most profound and beautiful question associated with the observed coupling constant, e the amplitude for a real electron to emit or absorb a real photon…(…It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.) Immediately you would like to know where this number for a coupling comes from: is it related to pi or perhaps to the base of natural logarithms? Nobody knows. It’s one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. You might say the “hand of God” wrote that number, and “we don’t know how He pushed his pencil…”

The first installment of this series may be found here, and it gives the basics as to how nuclear energy works.  The way that the stars generate their energy is interesting, and we shall consider it in greater detail this time.

Young stars almost always fuse hydrogen into helium.  There are several reasons for this, amongst them 1) hydrogen (protium, see the previous installment) is the most common nucleide in the cosmos, 2) more energy is released by fusing protium into helium nuclei than any other known process, and 3) there are multiple processes to accomplish it.

Hello, all.  This is sort of an irregular blog for me.  Except about myself, I rarely talk about other family members to protect their privacy.  However, this has been on national news, so their privacy is not very protected already.

Everyone is familiar with violence, at least on the news.  This piece affects me personally, and even though I watched some of the news feed in real time, it was after the medics had already left with the victims.

Hello, all.  I did not have research time to finish up the next installment about nuclear fusion in stars, so we will have to do with this.  I began planting my garden last week, so the subject of canning food came to mind.

Most people do not realize that canned foods are relatively recent developments, not counting wine and beer, which are at least technically, canned in many cases.

The sterilizations of indigenous women were covert means of the continuation of the extermination policy against the Indian Nations. At least three indigenous generations from 3,406 women are not in existence now as the result. The sterilizations were not unintentional or negligible. They were genocide. What would the indigenous culture and political landscape be now? One can only imagine, but the sterilizations like the relocations – were forced.

Nuclear fusion is often proffered as the final solution to our energy needs.  That well may be, but hardly anyone understands what it means, and almost no one, outside of physicists, knows how it relates to nuclear fission (the power source that we use now).

It all has to do with Dr. Einstein’s simple, but seminal equation, E = mc².  This means that mass can be converted to energy in a huge fashion.  Let us take a kilogram of mass, any mass, and convert it to energy.  Using the formula, and it has been proved over and over to be correct, one kilogram of mass (think of a big sirloin steak, for example) becomes a LOT of energy.

According to the equation, that kilogram of mass becomes thus:

E = (1 kg)(2.9979 x 10⁸ m/s)²  = 8.99 x 10¹⁶ Joules

This is almost 90,000 billions of Joules.  We are talking big energy.  But it does happen quite like this.  Only in matter-antimatter annihilation does all mass become energy.

According to the equation, that kilogram of mass becomes thus:

This is almost 90,000 billions of Joules.  We are talking big energy.  But it does happen quite like this.  Only in matter-antimatter annihilation does all mass become energy.

No more snow job photo diaries out of me. Since it is midwinter and everyone can use a little break from the cold, I think a little Brazilian Modern is in order.

How about you? Join me below for more photos and see an amateur review of my South American trip from last year.
