Most Unique World Records

Here’s a list of the most unique world records recoganised internationally, both human achievements and the extremes of the natural world.
Until 2000, the Guinness World Records was known as the Guinness Book of Records and it is the best-selling copyrighted series of all-time.
The interesting fact is that it is one of the most stolen books from public libraries in the United States.

How a Cpu Is Made

An absolutely fascinating step by step visualization

Sand. Made up of 25 percent silicon, is, after oxygen, the second most abundant chemical element that's in the earth's crust. Sand, especially quartz, has high percentages of silicon in the form of silicon dioxide (SiO2) and is the base ingredient for semiconductor manufacturing.

After procuring raw sand and separating the silicon, the excess material is disposed of and the silicon is purified in multiple steps to finally reach semiconductor manufacturing quality which is called electronic grade silicon. The resulting purity is so great that electronic grade silicon may only have one alien atom for every one billion silicon atoms. After the purification process, the silicon enters the melting phase. In this picture you can see how one big crystal is grown from the purified silicon melt. The resulting mono-crystal is called an ingot.

A mono-crystal ingot is produced from electronic grade silicon. One ingot weighs approximately 100 kilograms (or 220 pounds) and has a silicon purity of 99.9999 percent

The ingot is then moved onto the slicing phase where individual silicon discs, called wafers, are sliced thin. Some ingots can stand higher than five feet. Several different diameters of ingots exist depending on the required wafer size. Today, CPUs are commonly made on 300 mm wafers

Once cut, the wafers are polished until they have flawless, mirror-smooth surfaces. Intel doesn't produce its own ingots and wafers, and instead purchases manufacturing-ready wafers from third-party companies. Intel’s advanced 45 nm High-K/Metal Gate process uses wafers with a diameter of 300 mm (or 12-inches). When Intel first began making chips, it printed circuits on 50 mm (2-inches) wafers. These days, Intel uses 300 mm wafers, resulting in decreased costs per chip

The blue liquid, depicted above, is a photo resist finish similar to those used in film for photography. The wafer spins during this step to allow an evenly-distributed coating that's smooth and also very thin

At this stage, the photo-resistant finish is exposed to ultra violet (UV) light. The chemical reaction triggered by the UV light is similar to what happens to film material in a camera the moment you press the shutter button.

Areas of the resist on the wafer that have been exposed to UV light will become soluble. The exposure is done using masks that act like stencils. When used with UV light, masks create the various circuit patterns. The building of a CPU essentially repeats this process over and over until multiple layers are stacked on top of each other.

A lens (middle) reduces the mask's image to a small focal point. The resulting "print" on the wafer is typically four times smaller, linearly, than the mask's pattern

In the picture we have a representation of what a single transistor would appear like if we could see it with the naked eye. A transistor acts as a switch, controlling the flow of electrical current in a computer chip. Intel researchers have developed transistors so small that they claim roughly 30 million of them could fit on the head of a pin



After being exposed to UV light, the exposed blue photo resist areas are completely dissolved by a solvent. This reveals a pattern of photo resist made by the mask. The beginnings of transistors, interconnects, and other electrical contacts begin to grow from this point.




The photo resist layer protects wafer material that should not be etched away. Areas that were exposed will be etched away with chemicals


After the etching, the photo resist is removed and the desired shape becomes visible

More photo resist (blue) is applied and then re-exposed to UV light. Exposed photo resist is then washed off again before the next step, which is called ion doping. This is the step where ion particles are exposed to the wafer, allowing the silicon to change its chemical properties in a way that allows the CPU to control the flow of electricity





Through a process called ion implantation (one form of a process called doping) the exposed areas of the silicon wafer are bombarded with ions. Ions are implanted in the silicon wafer to alter the way silicon?i these areas conduct electricity. Ions are propelled onto the surface of the wafer at very high velocities. An electrical field accelerates the ions to a speed of over 300,000 km/hour (roughly 185,000 mph)


After the ion implantation, the photo resist will be removed and the material that should have been doped (green) now has alien atoms implanted.


This transistor is close to being finished. Three holes have been etched into the insulation layer (magenta color) above the transistor. These three holes will be filled with copper, which will make up the connections to other transistors.


The wafers are put into a copper sulphate solution at this stage. Copper ions are deposited onto the transistor through a process called electroplating. The copper ions travel from the positive terminal (anode) to the negative terminal (cathode) which is represented by the wafer





The copper ions settle as a thin layer on the wafer surface.




The excess material is polished off leaving a very thin layer of copper.






Multiple metal layers are created to interconnects (think wires) in between the various transistors. How these connections have to be “wired” is determined by the architecture and design teams that develop the functionality of the respective processor (for example, Intel’s Core i7 processor). While computer chips look extremely flat, they may actually have over 20 layers to form complex circuitry. If you look at a magnified view of a chip, you will see an intricate network of circuit lines and transistors that look like a futuristic, multi-layered highway system




This fraction of a ready wafer is being put through a first functionality test. In this stage test patterns are fed into every single chip and the response from the chip monitored and compared to "the right answer."



After tests determine that the wafer has a good yield of functioning processor units, the wafer is cut into pieces (called dies).


The dies that responded with the right answer to the test pattern will be put forward for the next step (packaging). Bad dies are discarded. Several years ago, Intel made key chains out of bad CPU dies


This is an individual die, which has been cut out in the previous step (slicing). The die shown here is a die of an Intel Core i7 processor



The substrate, the die, and the heatspreader are put together to form a completed processor. The green substrate builds the electrical and mechanical interface for the processor to interact with the rest of the PC system. The silver heatspreader is a thermal interface where a cooling solution will be applied. This will keep the processor cool during operation


A microprocessor is the most complex manufactured product on earth. In fact, it takes hundreds of steps and only the most important ones have been visualized in this picture story.



During this final test the processors will be tested for their key characteristics (among the tested characteristics are power dissipation and maximum frequency).

Based on the test result of class testing processors with the same capabilities are put into the same transporting trays. This process is called "binning". Binning determines the maximum operating frequency of a processor, and batches are divided and sold according to stable specifications.



The manufactured and tested processors (again Intel Core i7 processor is shown here) either go to system manufacturers in trays or into retail stores in a box. Many thanks to Intel for supplying the text and photos in this picture story. Check out Intel's site for full size images of this entire process.

Mystery of Argleton, the 'Google' town that only exists online

Argleton, a 'phantom town' in Lancashire that appears on Google Maps and online directories but doesn't actually exist, has puzzled internet experts. The town appears on Google Maps in the middle of fields close to the M58 motorway, just south of Ormskirk.

Its 'presence' means that online businesses that use data from the software have detected it and automatically treated it as a real town in the L39 postcode area. An internet search for the town now brings up a series of home, job and dating listings for people and places "in Argleton", as well as websites which help people find its nearest chiropractor and even plan jogging or hiking routes through it. The businesses, people and services listed are real, but are actually based elsewhere in the same postcode area.

Google and the company that supplies its mapping data are unable to explain the presence of the phantom town and are investigating. Tantalisingly, “Argle” echoes the word “Google”, while the phantom town’s name is also an anagram of “Not Real G”, and “Not Large”.

One theory is that Argleton could have been deliberately added, as a trap to catch companies that violate the map's copyright. So-called "trap streets" are often inserted by cartographers but are, as their name suggests, usually far more minor and indiscreet that bogus towns.

Roy Bayfield, head of corporate marketing at what would be Argleton's closest university, Edge Hill, in Ormskirk, was so intrigued by the mystery that he walked to the where the internet indicated was the centre of Argleton to check that there was definitely nothing there.

"A colleague of mine spotted the anomaly on Google Maps, and I thought 'I've got to go there'," he said.

"I started to weave this amazing fantasy about the place, an alternative universe, a Narnia-like world. I was really fascinated by the appearance of a non-existent place that the internet had the power to make real and give a semi-existence." When Mr Bayfield reached Argleton – which appears on Google Maps between Aughton and Aughton Park – he found just acres of green, empty fields.

Hairless Bear is Quite Frightening!!

I thought hairless cats were the most hideous creatures but I’ve got to say that this hairless bear is quite a competitor! In the same time, most of hairy creatures must look bad without their hair…

It may be funny at first, but it’s actually a sad story - vets don’t know why this female bear living at a zoo in Leipzig lost her hair. Moreover, it happened to all the other female bears of this zoo…


Hairless Bear is Quite Frightening!!
