Infinity and Infinitesimals - Part III
Next, what of negative numbers, and so-called imaginary numbers, such as the square root of -1? These numbers are found along a second and third axis, respectively, defining coordinates in a space existing along three dimensions when taken together with the first axis. The first dimensional coordinate axis is the axis I described with "1" at the center, the numbers less than 1 on one side and the numbers more than 1 on the opposite side. The second axis has -1 at the center, but the two sides are the numbers larger than -1 (like -0.Read more…Spooky Time
News from the scientific world tell us that there is a “warp” in the universe whereby the speed of light, and the passage of time, are so strangely related that the mere act of measuring them alters their performance.Einstein spent his life trying to find the “quantum mechanics” of nature whereby moving clocks run slower, and light travels faster, when we watch them. He called the phenomena “spooky action at a distance.Read more…The Ammonites-Index Fossils
Ammonites have been known to mankind for thousands of years. They are the source of many stories and myths. The name of this spiral-shelled cephalopod comes from the Egyptian god Ammon.Read more…Biological Factor
The division of environmental factors into chemical, physical, and biological is, of course, arbitrary and only done for convenience. There is bound to be considerable overlap. In so far as the food of marine plants is mainly inorganic salts and carbon dioxide, these have already been dealt with under the section on chemical factors.Read more…Migration
Probably a clearer understanding of migration may be attained if shorter movements are discussed first. Some movements of animals tend to lead them into new territory. Diurnal-nocturnal migrations are often important; insects and some vertebrates migrate from forest to grassland at night, returning to the forest for the day, there are also foraging cruises, as in those of the wolf group already mentioned.Read more…What is Biomimetics
For centuries Man has looked to the wonders of nature for inspiration. Leonardo Da Vinci designed ships with hulls based on the shape of fish and, less successfully, flying machines with the flapping wings of birds in flight. It took the Wright brothers to notice that large birds are unable to flap their winds repeatedly and glide instead, an observation that led them to design successful aircraft with fixed wing structures.Read more…A Comet over Russia - Literally
When many people think of comets hitting the Earth, they look to the far past. In truth, Siberia was home to a much more recent and dramatic event.Throughout the history of the Earth, many different celestial events have shaped our world.Read more…What Do Snakes Eat
There is no limit to the food items that you can even think of a snake might eat. Different species have different preys that they prefer to have. There are common preys that most of them like to have.Read more…Water Snakes
There are many types of water snakes found in the world. The type of snake you encounter depends on the region in which you are traveling. You should know that a snake could strike you from a distance of half of their body length.Read more…Female Brains vs. Male Brains
A new book that recently hit the market proclaims that women are much better than men when it comes to remembering the emotional times of their life.According to the new book “The Female Brain” by author Lou Ann Brizendine, women tend to remember the emotional events of their lives better than men because women’s brains are structured differently and contain a different set of chemicals than their male counterparts. The book cited scientific studies that used PET and MRI scans to support this conclusion.Read more…Tough Competitors? Just Hex Them
In modern society we have many means for dealing with tough competitors but putting hexes on them isn't usually one of our chosen methods. In Ancient societies, it was quite common. Archaeologists have recovered over 1,500 “Curse Tablets” from ancient Greece, England, Sicily, and throughout the Mediterranean and dating from as early as 500 BC, many of which do curse businesses and politicians.Read more…What is Molecular Biology
Molecular biology is the science of study of biology at the molecular level. William Astbury in Nature described molecular biology as:"... not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan.Read more…What are Antibodies
Antibodies, also called immunoglobulins are large y-shaped proteins which function to identify and help remove foreign antigens such as viruses and bacteria.In mammals there are five main types of antibodies including: IgA, IgD, IgE, IgG, and IgM. There are 4 IgG and 2 IgA subtypes present in humans.Read more…History And Uses Of Optical Microscopes
Optical microscopes use visible light and a system of lenses to magnify small samples that are usually un-seen to the bare eye. The optical microscope is the first, oldest and simples type of microscope (as opposed to the much more advanced electronic microscope). The first optical microscopes were created in the 18th century.Read more…Philosophy: John Lock
Locke improved Cartesian realism supposing that his empirical method allows him to explain the meaning of hidden essences in our guesses. Locke explained that humans’ secondary ideas do not allow to understand what cause them, while primary ideas are “qualitatively identical with their archetypes, thus affording us a conceptual bridgehead in reality itself”. Locke distinguished primary and secondary qualities stated that each object has its primary qualities, and other qualities which produced by power in the object itself are secondary.Read more…Hartmann's Mountain Zebras - Equus Zebra Hartmanni
Hartmann's mountain zebras are the largest of the mountain zebras. They look whiter than the Cape mountain zebras because their black stripes are narrower and more widely spaced.There are two kinds of mountain zebra.Read more…The Value of a Science Fair Project
With the jam-packed schedules of today's families, why would either a student or a parent want to add one more major activity? Clearly, any school project assigned to a student should meet a stringent test for usefulness. Surprising to some, a science fair project is one of the best learning experiences a student can undertake.Read more…Specifying Delay Lines
THERE HAS BEEN a tremendous growth in the computer, television and radar fields. As a result, the demand for components that give time control over pulse information has led to the development of a great variety of delay lines; delay lines that find use in systems that relate electrical information to time. Computers, television studios, telemetering systems, guided missiles, navigation systems, identification coders and decoders, radar systems and video tape recorders are typical systems that use delay lines.Read more…A Look At Four Incredibly Fun Toys That Help Encourage Kids To Love Science
If you want your child to have a love for learning which lasts a lifetime, you should start encouraging them early. Kids have a natural tendency to want to explore their environment and discover the world around them. A great way to instille a love for learning and an interest in science, one of the best things you can do for you child is get them a science toy.Read more…Science In Literature - Writers And Scientists Bridge The Gap
Fictional scientists are invariably portrayed as unscrupulous power seekers, out of touch with reality. At best they are caricatured as socially inept, white-coated misfits – think Jekyll, Frankenstein and Strangelove. All too often writers are forced to rely on these misguided stereotypes due to a lack of relevant knowledge and an understandable reluctance to seek help from experts who might disapprove of their ignorance.Read more…

- The Z-Boson Mass and its Formula as Multiple Proofs in One Bowl of Yummy Pudding - By: Sean Sheeter
A demonstration of the mathematical, theoretical and, especially, empirical connotations of the phrase "Pudding Proof" in the context of a highly exacting physical model. In particular, a formula is given deriving the mass of the Z-boson from two heavy quarks and and Higgs field. Remarkably, the precise correlation with the known value of the Z-mass is thus empirically proof positive of these far less directly measurable masses, which is further supported by arithmetic and theoretic construct. - The Theory, Significance and Precise Calculation of Gluino Mass - By: Sean Sheeter
A preview of the most significant predictable particle cascades at Cern's LH-Collider in the coming years. Describes how a precise gluino mass of 6.388355 TeV relates to the super-symmetric Higgs mechanism and decays to squarks and other 'sparticles as a prerequisite to creation of 'dark mass,' as well as the unsolved puzzle of material baryon creation. Which also goes on to shows why giving three dimensionless calculations for the gluino mass are central to the e-course "241-Mumbers." - Derivation of the Pure Precise Fine-Structure Number and as a Ratio of Two Inexact Metric Constants - By: Sean Sheeter
A history of a definitive answer to #1 'millennium question' of Strings 2000 in regard to whether all fundamental parameters can be determined in a dimensionless manner. Focus's on a 'pure' calculation of the fine-structure constant from a unified 'monolithic' system that allows precise equations for the full spectrum of fundamental particle masses from Higgs/SUSY to quarks, neutrinos and dark matter. With an update on controversies of determining the fine-structure from metric measures and a few other related issues. - Proof of the Exact Up and Down Quark Masses from the Pion Mass-Differential - By: Sean Sheeter
A discussion of the equivalence of the mass differential between the charged and neutral pion as a function the mass difference between the down and up quark. Given the unprecedented mass value of the down quark = 7.763258 MeV, the up quark mass is calculable from the even more exacting d-u mass differential = 4.593453 MeV, where the experimental pion mass difference = 4.5936 plusmn.0005 MeV. - Camps that Grow the Science in You - By: Ron Victor
If science is your child's much loved subject in the school, then it would be very worthful if you enroll him or her in any of the best science camp during summer vacation. - Why Are Some Scientists Doubtful about Subliminal Influence? - By: Evgheny Stivenson
Does subliminal perception really occur? Can anyone be able to observe something involuntarily without being conscious about it? These questions were raised to challenge the scientific validity of such claims. Experiments were conducted to prove that subliminal perception was indeed a fact. - Windmill site selection using Remote Sensing and GIS - A case Study in Andaman India - By: K Selvavinayagam
