Twenty Thousand Years of Memory 20091127

I mentioned the memory thing.  That is the strangest, other than living for so long, thing.  Those of us who have been given the gift hold memories, or at least fragments of them, from our predecessors.

I have not been specific about how this gift is transferred, but suffice it to say that it is nothing like a “bite on the neck” that does it.  I requires hours of extremely intimate contact, some, but not all of it, sexual.

Twenty Thousand Years of Memory 20091126

I was intentionally a bit obtuse about the number of years of my life, because it is easy to lose count.  I do remember when it started to get a bit warmer, and my people stated to be born with less hair, but before that I can tell you that it was bitterly cold, and without our own hair, in addition to the garments that we could fashion, death by hypothermia would have happened.

Our people were very well adapted for the cold.  We were “chunky”, in that we did not have as much surface to volume area as you moderns have.  But that “chunkness” only expressed itself if we were subjected to extreme cold.

Twenty Thousand Years of Memory 20091125

You do not know what it was like.  What you now know of as central Europe was cold as cold could be.  My people lived there.  We were Neanderthals.  Most moderns think that we were stupid.  We were not.

Nor did we look “odd” to you.  The skeletons that you moderns found were from our elders, and after three or four hundreds of years, of course they look primitive.  I assure you that they were not.  They were our elders that passed on the genetic trait of longevity that I have.

Pique the Geek 20091129: American Scientists. Robert Milliken. The Oil Drop Experiment

One of standard measurements that we take for granted these days is the charge of a single electron.  This is a vivid example of how scientific knowledge has exploded during the past century.  In 1870, there was no concept of an electron, and atoms were just very crudely becoming accepted.

After the turn of the previous century, it was generally accepted that there were atoms, and that electrons were likely a part of them, but no one knew much about them.  We still have not all of the answers, but Robert Milliken elucidated the intrinsic charge of the electron in xxxx.

Things That I do not Understand 20091124

As a professional scientist, I am accustomed to observing some phenomenon that is interesting to me, wondering about its significance, looking at background data (if any exist, and yes, “data” is the plural form of “datum”), and then trying to figure out the principles behind.

That works well, for the most part, in systems that can be controlled and only one variable at a time changed.  That is the essence of the scientific method as it generally practiced.  I dispensed with the classical steps, which are observation, formulation of a hypothesis, experimentally testing the hypothesis, refining or rejecting the hypothesis, and then doing more and better experimental tests to test the hypothesis further.  If one is very lucky, the refined hypothesis becomes a theory, and if no exception after crushing peer review, becomes a principle or a law.

Pique the Geek 20091122. US Coin Facts

United States coins have traditionally been forged and minted with gold, silver, and copper.  Very small amounts of other metals have also been added to improve the wearing properties of the coins.

Gold, silver, and copper, in their pure states, are actually too soft to make good coins, in that they wear must too fast.  The chemistry of good alloys is a fascinating part of numismatics, the study of coins.

I no Longer Support Univeral Health Care

I am sorry.  I really want a universal health care system.  Here is my take.  All voluntary reconstructive surgery will be taxed at 10% of the bill, the tax to be paid into the US Treasury.  This tax will not apply to reconstructive surgery from injury nor disease.

More to make it better?

Warmest regards,

Doc

Pique the Geek 20091115. The Things we Eat. Monosodium Glutamate (MSG)

Monosodium glutamate (MSG) is often used as a flavor enhancer in many savory dishes.  What most people know is that it often added to foods.  What most people do not know is that is present in many foods naturally, either in free form or as glutamic acid in proteins, since glutamic acid is a very common naturally occurring amino acid.

There is considerable controversy surrounding MSG, mostly due to the so-called Chinese Restaurant Syndrome (CRS).  Symptoms commonly reported include numbness and tingling of the extremities, facial flushing, and several others.  Tonight we shall take a fairly in-depth view of MSG.

I Loved a World War I Doughboy 20091111

I was reflecting this Veterans’ Day, and thought about John.  He was a good man, and I realized that I actually on very close personal terms with a World War I veteran.  By the way, there is, from what I have been able to find, only ONE American World War I veteran still breathing, and he is 108 years old.

John did not live that long.  He had a hard life.  He was also the most kind, most tender, and most loving man for kids that I have even known.  Please follow me on a very emotional track here.

Pique the Geek 20091108. Distillation, not Just for Beverages

Distillation is a technique of “squeezing” out the essence of a given material (or series of thoughts to one or a few abstractions) into a concentrated product.  The term is from the Latin, distillo, from the combining term de, meaning “down” and the noun stilla, a drop.  Thus, distilled water is literally a drop of water coming down something.  Taken to the extreme, distilled water literally means “a coming down drop of water that is water”.  That does not fit with the modern usage, but is illustrative.

Aristotle, with all of his faults, noted that seawater, boilt under cool sponges, would yield fresh water when the sponges were pressed.  Distillation was known in the ancient world, but not much used except for preparing “medical” remedies, most of them toxic, in a manner that I will describe to you later, in a more modern form.

Actually, the earth is a huge still, with the water cycle reproducing exactly, but on a massive scale, what goes on in an industrial or laboratory still.  Heating, evaporation, segregation of components, and condensation are all essential parts of distillation, and our planet does it well.  Without that process, the planet would not be recognizable.

Pique the Geek 20091101: A Primer on Nuclear Electricity

We shall get away from food for this installment of Pique the Geek and talk about something more, well, geeky.  The concept of nuclear power is widely known, but the actual way that is works is mysterious to some because people think that it is hard.  Actually, the basic science behind nuclear power is very simple, but the technology to contain and make it practical is complex.

This complexity is due to several reasons, not the least of which is safety.  Whilst the nuclear fuel to power commercial reactors is not very malignant, after that fuel has been used a while it becomes extremely radioactive due to a large number of complex nuclear interactions.  It is the spent reactor fuel that is the real problem.  However, there is a completely different technology used to generate electricity that does not involve a nuclear reactor, and we shall discuss this one first.

Nuclear Electricity, the Must Have for the Meantime 20091101

I know that this essay is likely not to be popular with progressive folks, but I am not only a progressive, I am a scientist as well.  In my opinion, the only relatively clean option for power that we have, other than natural gas (which is less plentiful and not as clean as the TeeVee adverts say) is the fission of uranium and plutonium.

I realize that this sounds pretty bold, but please bear with me whilst I build my case.  We need power in the meantime for the transition between fossil fuels and truly sustainable ones, and nuclear power is the only one that can provide that power.  First the physics, then the economics, and then the future.
