World of Science contains budding encyclopedias of astronomy, scientific biography, chemistry, and physics. This resource has been assembled over more than a decade by internet encyclopedist Eric Weisstein with assistance from the internet community. MeFi visited Weisstein's Mathworld a couple years ago.

The Spherical Wave Structure of Matter in Space

netbros — Fri, 30 Jan 2009 16:05:00 -0800

On Truth and Reality. Despite several thousand years of failure to correctly understand physical reality (hence the current postmodern view that this is impossible) it is actually very simple to work out how matter exists and moves about in Space. The rules of Science (Occam's Razor / Simplicity) and Metaphysics (Dynamic Unity of Reality) require that reality be described from only one single source existing, as Leibniz wrote: "because of the interconnection of all things with one another." The Four Main Purposes of this Website 1. To help people understand truth and reality 2. To realize that we are structures of the universe 3. To solve the central problems of knowledge 4. To share this knowledge with others Deduce the most simple science theory of reality, the wave structure of matter in Space, then deduce from this to show that it works. There is no opinion involved - it shows that science does work - we just needed the correct (most simple) foundations. Given the Wave Structure of Matter in Space it is now possible to explain what mathematics is, how it can exist in the universe, and thus why it is so well suited for describing physical quantities (mathematical physics). We can simplify Einstein's foundations of representing matter as continuous fields in space-time, to waves in continuous space. It does lead to a very simple, sensible foundation for understanding physical reality, and thus how you exist in the universe. This article basically explains the main subjects of quantum theory from a Wave Structure of Matter foundation (wave mechanics). If you prefer shorter summaries just browse the quantum physics links on either side of the page. The purpose of the Cosmology page is to simply explain the two cosmology theories that are consistent with current observations. You will need a basic understanding of the Wave Structure of Matter (WSM) before you read it. This WSM cosmology is actually describing what you really are, how you exist in this space of the universe and interact with everything around you. There is a revolution coming in the foundations of our knowledge because we have solved the central problem of metaphysics, of what exists (space) that causes and connects the many things we experience (waves in space that form matter, the discrete and separate particle an illusion of our limited senses). Matter is large, a structure of space, and this truth about reality will change humanity. If we are to discuss God and Religion, it is obvious that we must clearly define the meaning of these words (as all words are human constructions). In Philosophy God is generally referred to as the One thing that exists, infinite and eternal, that causes and connects the many things. Likewise, Religion, from Latin 'religare' meaning 'to bind', describes our connection to God as the One thing which exists. From this foundation we then see the clear connection between the sciences of philosophy, physics, metaphysics, and theology, as they are all founded on this Reality of One thing existing. As humans have evolved from Nature they ultimately depend upon Nature for their survival. Until we understand what we are as humans (what matter is) and how we are connected to the universe (reality), it is impossible for humanity to be wise, and to be able to evolve cultural knowledge that enables us to live in harmony with Nature. It is well known that our senses are deceptive, that when we see things as being separate and discrete bodies this is an illusion. Using science terminology then all we are really talking about is evolution and ecology. That all things in the universe (including life on earth) are interconnected and changing (the dynamic unity of reality). Teaching people how to think correctly and to use language carefully (to work out the truth for themselves) is a pretty good start for education (i.e. by teaching philosophy to students from a young age). If we are to improve human societies (which has become an urgent problem) we must consider the forces that determine their evolution. And four of the most significant factors are market economics, politics, education (the knowledge foundations of the people) and Nature.

Quark-Gluon Plasma

netbros — Thu, 18 Sep 2008 03:33:33 -0800

The ALICE Collaboration is building a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies. The aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected. This website aims both at introducing non-initiates to the field of physics covered by ALICE and at providing regular information on the evolution of the experiment, with detailed reports of its results and analysis.

Science Hack is a unique search engine for science videos focusing on Physics, Chemistry, and Space. For example, things to do with sulfur hexafluoride. Still growing, the editors are presently indexing other scientific fields of study including Geology, Psychology, Robotics and Computers. Ever wonder why things go bang?

The story of motion

Gyan — Thu, 17 Aug 2006 19:26:45 -0800

Motion Mountain - "The project aims to produce a simple, vivid and up-to-date introduction to modern physics, with emphasis on the fundamental ideas of motion. 'Simple' means that concepts are stressed more than formalism; 'vivid' means that the reader is continuously challenged; 'up-to-date' means that modern research and ideas about unification are included."

Physics is "phun"! (And "krazy")

RockBandit — Thu, 25 May 2006 00:04:12 -0800

Is this guy an awesome teacher or just crazy? Or maybe it goes hand in hand. Think back to the days of high school and college science classes. For most people, it probably wasn't chalkboards full of endless physics equations that got them interested in the sciences, but rather the crazy, cooky and awe-inspiring professors who do dramatic and unique demonstrations to get students interested. What makes a good teacher or professor? Is this teacher really reckless or is it a legit demonstration that benefits students?
