The Viking’s sword was his most prized possession. A good quality weapon was valued at about half a crown, and when you consider that this amount of money was worth the equivalent of 12 milk cows, these swords didn’t come cheap!
Archimedes of Syracuse, (c. 287 to 212 BC), a scientist, mathematician and reputed coiner of the word Eureka! developed the principle of buoyancy. It states that an object immersed in a liquid is buoyed up by a force equal to the weight of the liquid displaced by the object. On a small scale, a 1 carat diamond displaces 200 milligrams. On a much larger scale the 30,000 ton RMS Oceanic launched in 1899 displaced 30,000 tons of seawater.

Have you ever wondered how much technology has benefited from metal discoveries? Have you ever thought how metals have played a role in advances particularly in the medical field? It is very noticeable today how technology has made our life longer through its advancement. Medical advancement has saved many lives hence it is just right for us to revisit the discoveries in the metallurgy that made this possible.
In this article we are going to go over what reverse osmosis is. We are going to talk a little bit about how it is different from a filtration system and we are going to go over what the most common use for reverse osmosis is. If you are new to water treatment whether it be for your home or you business then you might be thrown a little of by the term reverse osmosis.
It is widely known that in the stable Lagrange points of Jupiter that there is lots of dust and debris, accumulated space particles that have ended up there and are caught in gravitational equilibrium between the fuzzy borders that make up the Lagrange point. And it is interesting that the dust and space debris is not necessarily at rest throughout the Lagrange area where it would be perfectly still. Why? Because around the fuzzy boundary areas there would be buffeting and movement eventually causing vortex flows.

Studying Anatomy and Physiology can be a very frustrating experience. At the beginning of my studies I was totally overwhelmed. There were so many bones, muscles, nerves, glands and tissues to learn and of course most of the words and names were in Latin which made it worse!
Everyone knows about this great woman Mrs. Currie, in fact, her name is Marie Sklodowska. She is known as the first famous woman scientist in the modern world and was called the “mother of modern physics”. The great Mrs. Currie made great contribution the modern physics and is the pioneer in research about radioactivity, which is a word she coined.
Theoretical physics blows my mind and I love it. Having taught it to both enthused and apathetic teenagers in past times, it’s now just a habit of thought, keeping up with the latest in cosmology. Garden rooms have a role to play, as investment and research budgets are slashed, in discounting the current apathetic acceptance that everything appeared from nothing, one Wednesday afternoon, 13.7 billion years ago.

Scientific discoveries have long been the greatest source of learning for the human beings. The ever increasing thirst of knowing more and more has forced the human being to make outstanding discoveries in the field of science. Some of these discoveries are truly unusual and has left us spellbound! Let us find out some of these unusual discoveries.
Most people think that Albert Einstein got Nobel Prize for his famous work on theory of relativity. But he actually got the award for his discovery of the law of photo electric effect.
Seismometers detect and record earthquakes. People sometimes use the word seismograph and seismometer interchangeably, but the seismograph is the output and the seismometer is the machine. Seismographs are the graph that the seismometer produces.
Let’s start with the very basics of the study. All matter (for example rocks and minerals) is made up of particles called atoms. Certain atoms form elements and the universe is made up of just over 100 elements, which stand-alone or with other elements, form compounds. The earth is made up of 8 elements. The earth’s interior is always changing because of heat and pressure. These changes in the earths crust cause rocks to form. This is a very well balanced system as the interior of the earth is under pressure and intensified heat; the outside elements also play a big factor in cooling the earth down.
Over the last few years, Superelastic Nitinol Wire has become the material of choice for the design of new medical products that rely on durability and flexibility when used for things like Nitinol stent for use in the heart. These innovations require that the smallest of wires need to be as flexible as possible, while retaining their high quality construction, and without degradation while inside the human body.
Everyone has seen a fluorescent tube light, the kind that are used in your kitchen or office and are more energy-efficient than the standard filament light bulbs.
The light itself uses a number of electrical processes that are similar to those used to generate thrust from a plasma engine in space, yet few of us would make the connection between the two. A way to look at it is this: the process that lights a lot of public and private spaces is almost identical to the process that can propel a spacecraft towards another planet or in the case of the NASA probe, Deep Space 1, can propel a craft to speeds never achieved previously in space travel. Plasma engines are viewed as next-generation technologies, with large-scale thrusters currently being developed for possible use on interplanetary missions; however ion thrusters, a class of plasma engines, are currently being used on missions to provide station-keeping duties or as the primary propulsion for spacecraft.
Expensive is one kind of the language that men and women today use to spell out power bills. Apparently daily, the expense of energy retains obtaining increased and higher. Due to this, all of us have a tendency to choose sustainable energy options.
Stability testing chambers are enclosures used to assess the effects of pre-specified environmental circumstances on biological materials and industrial/electronic components. The most common use of these stability chambers (sometimes referred to as environmental chambers) is that of stand-alone specimen testing for decomposition and reduced efficiency under various temperature and humidity ranges.

Fiber optic networking stands for modern communication means permitting high quality transfer via light impulse. Fiber optics has changed the standards when it comes to top performing means of communication. However, experts explored the benefits of optics thoroughly, ever since they developed the first optic camera. This unit is the ultimate innovation in security systems because it enables filming in very special circumstances, more precisely, it provides a wide angle view, contrasting with the hardly noticeable camera which is positioned so that its presence will not be detected. Fiber optics have refashioned communication simply because older transmission means cannot compete with new performance standards, which optics have set in terms of data transfer. Signal transfer and, implicitly, information transfer reach a higher quota when the network is made out of optic cables.
“The change from sandstone to granite as one leaves Jebel Mukatteb and winds along Wady Feiran is very striking. Even to the most uneducated eye the colours tell their own story of chalk and limestone and sandstone and granite. The mountains are streaked from head to foot as if boiling streams of dark red matter poured over them, the vast heaps of seemingly calcined mountains, the detritus iron in The sandstone formation, the traces of igneous action on the granite rocks are dating from their first upheaval” Sir Charles Wilson, Picturesque Palestine.
Nanotechnology, a branch of Nanoscience, is the latest craze among academia, media, and all other kinds of industry. Nanotechnology can be vital even for investors who have realized its advantage. Nanotechnology is also becoming an increasingly interesting area in the field of the law as well. Due to Nanotech huge law documents can be shrunk into the size of a sugar cube.
IB Physics, especially at the Higher Level, is one of the most difficult subjects in the IB Diploma. Nonetheless, it is still very possible to attain a 7. In fact, according to the IB Statistical Report in November 2009, 31% of Standard Level Candidates and 20% of Higher Level Candidates received a 7. This means that on average, in a class of 20 HL students, 4 will get a 7.
