Louis Essen was born in 1908 in a small city in England called Nottingham. His childhood was typical of the time and he pursued his education with enjoyment and dedication. At the age of 20 Louis graduated from the University of Nottingham, where he had been studying. It was at this time that his career started to take off, as he was invited to join the NPL, or National Physics Laboratory.
It was during Louis’s time at the NPL that he began working to develop a quartz crystal oscillator as he believed they were capable of measuring time as accurately as a pendulum based clock. Ten years after joining the NPL Louis had invented the Essen ring. This was an eponymous invention which took its name from the shape of the quartz which Louis had used in his latest clock and which was three times more accurate than the previous versions.
Louis soon moved on to newer areas of research and began to study ways to measure the speed of light. During World War II he began to work on high frequency radar and used his technical ability to develop the cavity resonance wavemeter. From 1946 it was this wavemeter which he used, along with a colleague by the name of Albert Gordon-Smith, to make his lightspeed measurements. It has been acknowledged recently that Louis’s measurements were by far the most accurate to have been recorded up until that time.

During the early part of the 1950’s Louis began to take an interest in research which was being carried out at the National Bureau of Standards (NBS) in the United States of America. He learnt that work was being carried out to invent a clock which was more accurate than any other. The American scientists were using the idea of maintaining a clock’s accuracy by using the radiation emitted or absorbed by atoms. At that time the Americans were using a molecule of ammonia but Louis felt that this was not working as well as if they were using different atoms, such as hydrogen or caesium, and so he began working on his own clock using these materials instead.
1953 saw Louis and a colleague, Jack Parry, receiving permission to develop an atomic clock at the NPL based on Louis’s existing knowledge of quartz crystal oscillators and other relevant techniques he had learned from the cavity resonance wavemeter he had previously designed. Only two years later Louis’s first atomic clock was running, Caesium I, designed by the UK scientists. Development in the United States had all but stopped due to political difficulties.
Louis continued to work on his atomic clock and by 1964 he had managed to increase the accuracy of the atomic clock from one second in 300 years to one second every 2000 years! The continued success of Louis’s work resulted in the definition of a second being changed from 1/864000 of a mean solar day to being calculated as the time it took for 9192631770 cycles of the radiation in an atomic clock.
Louis Essen died in 1997 and before his death had been honoured with, amongst others, an OBE and the Tompion Gold Medal of the Clockmakers’ Company.

It was mentioned on a biology blog that archaeological engravings from the Tiwanaku civilization in Bolivia are unlikely to be depicting an ancient astronaut for the reason that, even with an aquatic tail, the creature still looks too much like a human. The underlying argument was that the evolution of life forms is so diverse that it is highly unlikely an alien would come out looking even remotely like us. In essence, this is the opposite side of the pendulum to Hollywood’s consistent imaging of aliens as humanoids.
The biologist ignored the decorative and symbolic imagery added by the Tiwanaku artists and did not consider the given premise of an aquatic alien inside helmeted spacesuit. I have to assume, therefore, the biologist noted that the creature had two arms and two eyes, and since humans have two arms and two eyes, the biologist concluded that this cannot be an alien.
What should intelligent aliens look like? Or, to phrase it another way, what should we expect interstellar travelers who come here to look like? This is not a complete unknown. If the aliens are capable of interstellar travel, they obviously achieved higher technology. What is necessary to achieve technology? My opinion on this is that to achieve technology, a life form would need a complex brain and the ability to see and manipulate objects. This implies eyes, fingered appendages, and perhaps a head relatively large compared to overall body size. The Tiwanaku alien has all these features.

The biologist might counter that the issue is not that aliens have eyes, but the number of eyes. Here on Earth, higher animal forms evolved with two eyes. For example, mammals, birds, fish, reptiles, and insects all have two eyes, but on another planet the number of eyes would be different. There, perhaps, the life forms would randomly have one, three, four, or even ten eyes. Is that true? Is the number of eyes a random event in the evolutionary process?
Astronomers searching for extraterrestrial intelligence are looking for planets similar to Earth regarding temperature and chemical composition because they know life evolved here, so it is logical to assume that life might also evolve on other similar planets. Likewise, with similar planetary history, we might expect the evolutionary process on those other planets to progress similarly to how it progressed here.
Question: Was the evolution of animal life with two eyes on Earth a random event, so much so that we should expect extraterrestrial life to have a different number of eyes? I think not. Why? It is called natural selection or survival of the fittest. Two eyes are the minimum required to give depth perception and concentrated focus. Perhaps early on Earth there were animals with five or ten eyes, but with a brain too small to orientate five directions, such species quickly became extinct. Only two eyes survived. Should we expect something radically different on another Earth-like planet? No. It is reasonable to expect intelligent aliens to have two eyes, just like humans.
It is also reasonable to expect alien life forms to be imaginable from the diversity of life forms we see on Earth, past and present. The Tiwanaku alien has features similar to a fish (fish mouth that seems to be breathing inside a water-filled helmet), features similar to a lobster (sea creature with two forward appendages for manipulating objects), and features similar to humans (large head and fingered upper appendages). Only four fingers are depicted in the Tiwanaku drawings, versus our five, but this easily falls within evolutionary feasibility. The alien’s three-pod aquatic tail is also an imaginable evolutionary development.

I think the biologist’s appreciation for the potentially enormous diversity of life forms in the universe is admirable. For those life forms that develop higher technology, however, it is likely, not unlikely, that they will have something in common with humans.
This article referred to Bella Online Biology comments on the Tiwanaku Alien pages of the CrypticThinking.com website.

You may have experienced having your computer intermittently hangs-up, or may re-boot itself for no apparent reason. It is almost like a 3 point basketball shot as the buzzer; it’s going, and going and going then it hits the rim and it is all crapped out like your computer freezing up. This can be annoying, and can mean you have lost valuable work that you we in the process of creating.
If this has happened once, then your chances of explaining the cause are remote in the extreme. If you find it happening regularly, then it is clearly in your interest to find and fix the problem.
There are a few things you can check for yourself that may save you a trip to the repair shop.
With most modern computers, the system comes with built in circuitry to monitor the state of the computer. One of the checks built into your system is to test the operating temperature. The computer may shut down if this moves outside the desirable operating range.
For your system to run at the correct operating temperature it is important that air circulates freely in and around the case. If you have the computer case installed inside an enclosure, then this may be the first thing to consider changing. Similarly, I have seen computers covered with books, manuals and paper documents. These again can hinder air circulation, and these items should be removed. Take a look at the slotted vents in the sides of the case. These slots can become blocked by an accumulation of dust. Because the computer is usually always drawing some power, it has a constant electrostatic charge. A computer is second only to a vacuum cleaner in its ability to suck in dust and fluff.
Let’s take a moment for a pretty picture.
This picture was shot 2010-05-13 at Hood River of the Columbia River Bridge.
We will now continue with the blog. Like the picture?
Taking the cover of the case will also show the dust build-up inside the computer. Be careful removing dust accumulations from internal components. This is probably best done with a soft artist’s brush or an aerosol can of compressed air.
Next, take a look at the internal cooling fans. Modern computer usually have a cooling fan perched on top of the processor. This fan should be clear of dust, and running freely, without obvious scraping noises, when the computer is operating. It is OK to start the computer with the case cover removed, just be careful not to poke things into the various components.
There will also be a cooling fan inside or attached to the power supply. This again should be free of dust and running freely. Some computers may also have an additional case fan. This will be screwed on over one of the slotted case vents, and typically be running from a cable connected to the mother board. Not all machines have a separate case fan, but if it is there, it is there for a reason. Apply the same checks to this fan.
If you have identified faults with your cooling fans, this may require a trip to your local repair shop. The repair technician may also suggest that the CPU heat sink be removed and re-placed with fresh heat transfer compound, which is a straightforward job for an experienced repairer.

Corn pollen more than 80,000 years old was found in Mexico. Proper popcorn was known in China, Sumatra, and India for at least 5000 years. Popped popcorn and kernels 5600 years old were discovered in the “Bat Cave” in New Mexico in 1948-1950. Popcorn kernels – ready to pop – were unearthed in ancient Peruvian tombs. In a cave is southern Utah, fluffy, fresh looking, white popcorn was dated to 1000 years ago.
Let’s Take a moment from this blog and look at a pretty

Now back to the Blog.
Popcorn was used by the Aztecs and Indians as a decorative motif in headdresses, necklaces, and ornaments on statues of divinities. In the 16th century, both Hernando Cortes (in Mexico) and Christopher Columbus (in the West Indies) described these unusual uses of the snack. Father Bernardino de Sahagun (1499-1590), a Franciscan priest with deep interest in Mexican culture, described a ritual in honor of the Aztec gods of fisheries:
“They scattered before him parched corn, called momochitl, a kind of corn which bursts when parched and discloses its contents and makes itself look like a very white flower; they said these were hailstones given to the god of water.”
French explorers in the early 17th century reported that the Iroquois Indians in the Great Lakes region drank popcorn beer and ate popcorn soup. In either 1621, or in 1630, popcorn was brought as a gift by the Indian Quadequina, brother of Chief Massasoit of the Wampanoag tribe, to the colonists in Plymouth, Massachusetts at their first Thanksgiving dinner in the new land.
This may be an apocryphal story but, in any case, it would not have been popcorn as we know it today. An oiled ear was held on a stick over an open fire and the popped kernels would be chewed off. Popcorn later served as a morning cereal, eaten with cream or milk. The colonists called it “popped corn”, “parching corn”, or “rice corn”.
Most of the world’s popcorn (“prairie gold”) is produced in Nebraska, Iowa and Indiana, in the United States. The kernel is a seed containing a plant embryo and its soft, starchy food. The seed is protected by a hard shell. Heating the kernel converts water held in the seed into pressurized steam which causes the kernel to pop and the starch to expand to 40 times its original size.
