Large Hadron Collider

8 07 2008

The gigantic scientific instrument called Large Hadron Collider has to be started up today in a world’s largest and most respected centre for scientific research near Geneva at the border Switzerland and France about 100 m underground. This grand scientist experiment will help physicists to learn more about the laws of Nature. What is the result we should expect from such grandioso human’s practical activities on the Earth? There are many theories and discussions about. But the main goal is finding out what the Universe is made of and how it works.

Do you think the answer will be found soon? I don’t so. But no doubt today is the beginning of the process.





ATLAS and CMS

26 06 2008

While the discussion about ATLAS and CMS, general-purpose particle physics experiments is continuing scientists do their work. The ambition project called for help to see a wide range of particles and phenomena produced in LHC collisions has involved approximately 2,000 physicists from some 35 countries.

They will use the data collected from the complex ATLAS and CMS detectors to search for new phenomena, including the Higgs boson, super symmetry and extra dimensions. They will also measure the properties of previously discovered quarks and bosons with unprecedented precision, and be on the lookout for completely new, unpredicted phenomena.

What is Higgs boson? This is “a fundamental particle predicted by theorist Peter Higgs, may be the key to understanding why elementary particles have mass”, Howard E. Haber from University of California, Santa Cruz explanes. “Explaining the connection, I am reminded of the puzzler, “If sound cannot travel in a vacuum, why are vacuum cleaners so noisy?” This riddle actually touches on a profound insight of modern physics: the vacuum—or empty space—is far from empty. It is indeed “noisy” and full of virtual particles and force fields. The origin of mass seems to be related to this phenomenon.
In Einstein’s theory of relativity, there is a crucial difference between massless and massive particles: All massless particles must travel at the speed of light, whereas massive particles can never attain this ultimate speed. But, how do massive particles arise? Higgs proposed that the vacuum contains an omnipresent field that can slow down some (otherwise massless) elementary particles—like a vat of molasses slowing down a high-speed bullet. Such particles would behave like massive particles traveling at less than light speed. Other particles—such as the photons of light—are immune to the field: they do not slow down and remain massless.

Although the Higgs field is not directly measurable, accelerators can excite this field and “shake loose” detectable particles called Higgs bosons. So far, experiments using the world’s most powerful accelerators have not observed any Higgs bosons, but indirect experimental evidence suggests that particle physicists are poised for a profound discovery.”





Facts and Myths about Brains.

10 05 2008

Recently The Daily Mail has published very fascinating facts and common myths about our grey matter, I mean our brains of course. These facts and myths have been taken from a new book by two leading neuroscientists Sandra Aamodt and Sam Wang. The information is interesting and sometimes really surprised.

FACT: You can’t tickle yourself
When a doctor examines a ticklish patient, they place one of the patient’s hands over their own to prevent the tickling sensation.
Why does this work? Because no matter how ticklish you may be, you can’t tickle yourself.
This is because your brain focuses on what’s going on in the outside world — to prevent important signals from being drowned out in the endless buzz of sensations caused by your own actions.
For instance, this means you’re unlikely to notice the texture of your socks, but you would feel a tap on the shoulder.
The patient doesn’t feel the tickling because his brain thinks it’s his own hand doing the action.
FACT: Looking at a photograph is harder than playing chess
When computer scientists first began trying to write programmes to mimic human abilities, they found it relatively-easy to get computers to follow logic and do complex maths — such as those required in chess moves — but very hard to get them to figure out what they were seeing in a visual image.

Today’s best computer programmes can beat a grand master, but any toddler can beat the top programmes when it comes to making sense of the visual world.

One reason for this is the difficulty in identifying individual objects.

You only see this ambiguity when you see something briefly enough to misidentify it — like when that rock in the middle of the dark road suddenly turns out to be a neighbour’s cat.

MYTH: You only ever use about 10 per cent of your brain
Although half the world’s population thinks this, in reality you use your whole brain every day.
But for the myth to stick around for so long, it must have been saying something that we really want to hear.

In fact, its impressive persistence may depend on its optimistic message: “If we use only 10 per cent of our brains normally, think what we could do if we could use even a tiny bit of that other 90 per cent.”

The truth is, studies of brain activity show that even simple tasks actually produce activity throughout the entire brain.
More about this book you can read in my Library. So welcome to your brain.





HDMI Cables.

15 04 2008

Usually all of us using different types of cables and connections don’t think too much about how it works and what happens inside. All what we need is its work must be irreproachable. If you have bought or just going to Buy HDMI Cables you’ve probably heard about HDMI and it seems like just one of many connections on televisions or home-theater receivers. That’s right, but not only.

Comparing different system cable’s connections experts have marked HDMI as having wider screen, more pixels and a faster refresh rate, besides that HDMI system is able to display more colors than other sets and this leads us to it. So HDMI is a set of guidelines for creating high-bandwidth connections between digital devices and with the right setup, it can make a significant difference in a home-theater or PC system then no wonder that HDMI has become more popular than Digital Visual Interface, or DVI. It’s easy to use and supports a TV and PC format. It allows you to get the best combination of your audio and visual world.





Telephone Communication.

2 04 2008

The modern name “telephone” as a device that enables us to hear sound at a distance comes from two words,- tele, meaning ‘at a distance’ and ‘phonic’ referring to ’sound’. And in spite of the credit for inventing the electric telephone remains in dispute however among others well known names we can call such famous ones as Charles Bourseul, Antonio Meucci, Johann Philipp Reis, Alexander Graham Bell and Elisha Gray. Thanks to them and many others inventors all of us today are familiar with the telephone as a means of communicating with one another.

But as a matter of fact telephone was invented not too long ago, the first message or ‘telegram’ sent by a telegraph using electromagnetism was in 1833, several different models were produced by two Englishmen, Cooke and Wheatstone. Electric currents passed down wires deflected magnetic needles which pointed to the letters arranged on a panel. The first telephone station was biult in US in 1877, only 131 years ago. I’m not sure that’s only or already but actually 131 years is not too long period for such revolutionary changes we have watched, isn’t it? However, the modern telephone is the result of work done by many people, all worthy of recognition of their contributions to the field and now we just cant emagine our everyday life without this fantastic device.

New technological advancements, mobile technology and wireless technologies have done much to change the way we live and communicate over the past quarter century. I can hardly imagine today businesses management without daily Conference Calls using to meet with remote parties, both internally and outside of their company. Audio Conference provides the client meetings or sales presentations, project meetings and updates, regular team meetings, training classes and communication to employees who work in different locations. Call Conferencing is viewed as a primary means of cutting travel costs and allowing workers to be more productive by not having to go out-of-office for meetings.





Robot Big Dog.

20 03 2008

Watching the Big Dog lifelike moves and balances I was filled with mixed feelings. I would not like to meet this monster tête-à-tête :-) But it’s really good job! The robot was created by Boston Dynamics Inc and you can see here its climbing through the woods, through snow, and recovering its balance while trying to negotiate an icy parking lot. Bravo creators!

Boston Dynamics engineers were contracted to develop a robot with the ability to run, maneuver and jump to avoid obstacles. The robot would measure 1 meter tall and 2 meters wide, according to the U.S. Department of Defense. The goal of the project, which was slotted to last 15 months, is to produce a robot with animal-like strength, speed and mobility, according to defense officials.

The DARPA contract, which was commissioned by the Space and Naval Warfare Systems Center in San Diego, includes three one-year contract renewals valued at total of $40 million.





Truly Wireless Battery Invention.

7 03 2008

Konarka Technologies, Inc have demonstrated new light-activated Power Plastic Sun Battery, that is flexible, lightweight, lower in cost and much more versatile in application than traditional silicon-based solar cells.

These new materials are made from conducting polymers and nano-engineered materials that can be coated or printed onto a surface in a process similar to how photographic film is made.

Batteries can be useed with devices, systems and structures to have their own low-cost embedded sources of renewable power. By combining energy generation and power consumption within the same device, the battery is truly wireless applications.





Apple, Touch Panel, RFID readers.

27 02 2008

As it became known Apple Corporation had tendered the US patent agency with a new invention which will give users of sensor screen gadgets more operative possibilities. The innovation will let users just using up their fingers to cut, copy and paste fragments of text and to work with files. This is a logical pace and it was to be certainly expected.
At the moment the company produces the Smartphone iPhone and multimedia player iPod Touch with multi-sensor displays. Their capabilities and the capabilities of notebooks Macbook Air with the analogical touchpad Apple in the document are called referring to the “major.”

Touch Panel monitors have become more and more popular and can be easely attached now to both home PC and Industrial Computer or used as a terminal to networks. The line of operator interface touch panels is one of the most powerful and easy to use in the industry, using it you can virtually replace almost all mechanical pushbuttons, switches, meters, and other peripheral devices. Also it has assisted in recent changes in the design of personal digital assistant (PDA), satellite navigation, mobile phone and security devices integrated radio frequency identification RFID readers and RFID making all these devices more handy and usable.

What kinds of gadgets and gizmos will make our daily lives easier? Do we expect some day cell phones and PDAs with GPS will be integrated into our bodies and individual air vehicles will whisk you anywhere you want to go? I think so. The science of today is the technology of tomorrow.





Gaming As a Life.

20 02 2008

“You have to learn the rules of the game. And then you have to play better than anyone else.” Albert Einstein said and that is very right because great scientist meant not only game as such but the life of course. Since the first arrow hit the mark, since first Greek games, even since the first checker was crowned king, man pits his talents against others in games of strength and skill. Nowadays computer games as a form of mass entertainment have enormous worldwide popularity and it’s no wonder! Many kinds of Online Games give us an opportunity not only to try our strength but just to use it as a welcome diversion from the humdrum of everyday life. There are numerous RPG and strategy games, puzzle and word games, Shooting Games, funny games, skill games, Racing Games, online geography games, learning games for kids and many web based with hundreds or thousands of players you can find online.

So you have got a great chance to choose whatever you wish to play and whenever you want. There are computer games, in which players create characters in a virtual world and interact to solve problems or win battles, are branching out from fantasy into serious social issues. Today computers games give us the great opportunity for choice and playing game one can not only spend the time magnificently but also to learn picking up serious, with meaningful issues games.

So playing a game we learn the rules of life and become better players of the game.





Bio-Electromagnetic Weapons.

18 02 2008

At the beginning of February the U.S. Navy test fired an incredibly powerful new big gun designed to replace conventional weaponry aboard ships. New weapon uses electromagnetic energy instead of explosive chemical propellants to fire a projectile farther and faster. The railgun, as it is called, will ultimately fire a projectile more than 230 miles (370 kilometers) with a muzzle velocity seven times the speed of sound (Mach 7) and a velocity of Mach 5 at impact.
The test-firing, captured on video, took place Jan. 31 in Dahlgren, Va., and Navy officials called it the “world’s most powerful electromagnetic railgun.”

“I never ever want to see a Sailor or Marine in a fair fight. I always want them to have the advantage,” said Chief of Naval Operations, Admiral Gary Roughead. “We should never lose sight of always looking for the next big thing, always looking to make our capability better, more effective than what anyone else can put on the battlefield.”

What is Bio-electromagnetic Weapons?
This is an ultimate weapon system that operates at the speed of light; they can kill, torture and enslave; but the public are largely unaware that they exist, because these weapons operate by stealth and leave no physical evidence. Electromagnetic weapons have been tested on human beings since 1976 and according to “Science in Society” this weapon was being deployed in Iraq.

There is only one electromagnetic spectrum. Nuclear weapons release a great deal of ionizing radiation in the high frequency range above visible light, where the energy of the radiation is capable of breaking chemical bonds. The beginning of working up started in 1959 when Saul B. Sells, a professor of social psychology at a minor US university submitted a proposal to the Central Intelligence Agency (CIA) to build for them the most sophisticated electroencephalography machine that would have an integral computational capacity to analyze and, hopefully, make sense of the brain waves it recorded. In other words, the professor proposed to make a machine that could tell the CIA what a person was thinking, whether or not the person wished to disclose that information. In 1973, Joseph C. Sharp, an experimental psychologist at Walter Reed Army Institute of Research performed an experiment that was pivotal to the development of the torture equipment being shipped to Iraq today. He had James Lin set up equipment in his laboratory which converted the shape of sound waves into microwave radiation that enabled him to hear himself vocalize the names of the numbers from one to ten in his head, by-passing the mechanism of his own ears. This particular experiment was never published but is mentioned in Lin’s book, Microwave Auditory Effects and Applications, published in 1978.

Today after the weapon test we can definitely say that the inevitable has occurred! But what is in store for us in future? I don’t thing it will be something good. Any weapon wants to be used.
