DNA Fingerprinting
In criminal cases, it is the strength of the evidence against the accused that determines the outcome of the case. This is why prosecutors try their best to come up with the strongest evidence to prove the guilt of the defendant, and this is also why defense lawyers try their best to discredit the evidence of the prosecution. To help them do this, both the defense and the prosecution solicits the help of experts in analyzing evidence and in proving the veracity of the evidences in the case.Read more…DNA Structures
In all that we see in nature, the principle that we usually see is that form follows function. This is because in almost all creatures and plants, the unique features that they have serve a purpose. One example of this includes how some creatures are able to camouflage themselves within their background because their skin color allows them to do so.Read more…Is There a Waterproof Solar Charger?
Many people using solar chargers want to know if there is a waterproof solar charger available. Most of these people who like to use their solar chargers while at the beach are afraid that the water splashing around will ruin their chargers.

So what of numbers, such as 2, 11, -1028, or 15i? While the conventional understanding of numbers is that they can be arranged in a series such that at one end you have the smallest and at the other end you have the largest, this concept can be true only in a relative sense, as in the comparison of one finite quantity to another finite quantity. In terms of Reality, all finite numbers, including so-called whole numbers, are fractional.Read more…If You Could Clone
Having tied at 101 -- with so many others -- in the Sun’s recent “Charlotte County’s Hundred Most Powerful,” I invite those who didn’t make the cut to join in a more sophisticated game of “If You Could Clone.”This new game is doubly significant because of the current hullabaloo over human cloning.Sufficient here is the supposition that a single, biological cell – living or preserved -- contains all the genetic DNA necessary to create a replica of the person from whom the DNA came.Read more…The Chronosphere - Revealing the Nature of Time
The conventional view of physical life is linear. By "linear", I mean the concept that the lives we live can be described in terms of a progression beginning at birth, through the past to the present, then to the future and ending at death. This is often referred to as a "timeline".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
