A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are — a phenomenon known as quantum entanglement.
In previous studies, photons have typically been entangled by one dimension of their quantum properties — usually the direction of their polarization.
In the new study, researchers demonstrated that they could slice up and entangle each photon pair into multiple dimensions using quantum properties such as the photons’ energy and spin. This method, called hyperentanglement, allows each photon pair to carry much more data than was possible with previous methods.
Quantum entanglement could allow us…Read more >
Hi people this is draken. I am back again with the 'When we divide by a #' series blog. Now I had created a blog about dividing numbers by seven and it still is in beta mode. The thing is I won't be editing it anymore until someone comes and helps me in the pattern the thing was that uhm...it was very tough working with the division of a numebr by 7. Real tough man! So I ceased research on it but now I am back with a very simple one. The pattern is very easy and simple to understand and remember in this one. Let me show you.

Hello guys, Draken here. Now the thing is that uhm... well, this is not really a real edit. I mean I really haven't come up with a text material so this blog is still in its beta position but I have got some of the data already collected and formatted into a table so that you guys can check the way things are happening when we divide by seven. The last three column headings containing the number '4, 7 and 8' actually tell where a non-recurring corresponding number is occuring. Just look at the data below and you will see.
Conclusion:So I would conclude that this blog is not fully formatted and edited yet because I lack some text material for this blog which will come soon!Read more >
9 is a number (obviously) and it has many uses as well as all the other numbers in the world. But today, I am going to focus on telling you some tricks on how to find the answer to a "Read more >
Hello guys, it has been a long time... well, to be exact it has been 17 days or 408 hours or 24,480 minutes or 1,468,800 seconds.. some calculation, huh? I used a calculator! So I love to experiment with numbers and arithematics and all that thing. I mean I love math. I love playing with numbers and all that stuff. Due to this reason only I have been able to remember the Multiplication Table upto 25! So... in one of my previous blogs titled 'When we divide by 9' we observed a pattern in the series of division of natural numbers by 9. It was a very fascinating... Well this one's going to be more fascinating than that! So let's roll.
Now, if you are interested in the process of this problem then please keep a rough notebook and a pen/pencil …

The Kepler Mission has a simple objective: find small planets around other stars - worlds like Earth that could possibly spawn life. It promises to be one of the most exciting astronomy projects of the coming decade.
In the last half-dozen years, astronomers have made a remarkable discovery: roughly 5 - 10% of stars similar to the Sun have planets. They have observed this fraction of stars to periodically wobble in response to the orbital motion of unseen worlds. However, every one of the planets detected by this method is hefty, typically the size of Jupiter or larger. This preponderance of massive worlds is an inevitable consequence of the detection scheme: only large planets induce measurable wobbles.…Read more >

A college student Joe Landolina creates a gel like mixture for armies and the navy to use when injured. The mixture is "Smart Bio Material" according to Joe Landolina, that works with the body meaning it is not for one type of cell tissue called Extracellular Matrix (aka ECM) which contains cells. This gel is a miracle because not all gels that stop bleeding instantly will form around that individuals Extracellular Matrix. Joe Landolina says he hopes to get this gel out to the public in a year.
"Imagine you are a soldier at the battle field. Now, you get hit with a bullet and you a bleeding badly. This wound will only take 3 minutes to kill you but by the time the medics arrive you will already be dead. Now imagine you have this gel that …Read more >

Scientists and Doctors have proven that frozen feces in pill form from a healthy individual can treat/cure a potential killer disease. I know, it sounds gross! Ilan Youngster, a physician, did a new study. He took healthy gut bacteria from donated stool/feces. Then, they froze the microbes into capsules. “This greatly prolongs the shelf life of the microbes” says Science News. Ilan’s research team gave capsules of the frozen stool/feces to 20 patients that had C. diff infections. 14 out of 20 patients had their infections cleared by taking two day regimens with this new capsule. Thats incredible!
And gross! The four people that weren’t cured, were cured after the second round of capsules. The researchers reported that t…Read more >
I have decided to write a blog about me so you guys can get to know me better. I started kindergarten when I was 4 years old (early, right?) and I have been wanting to learn ever since. In 6th grade I got the "Best Technology Student Award" for being a so called "tech-geek" and for helping students with laptop problems. I love technology and how it works and I also love how technology ties in with Science and Math. I am currently in 7th grade right now and I currently take Spanish, General Music, STEM, Social Studies, Math, Science LA, Drama, etc.
I volunteer at the school library, and so I check out books for students and check books into the library. I also put books away and make new covers for the books that need them. As I said above, I…Read more >
Okay so I haven't watched this movie yet but already read its plot and trailer on the internet. The movie is awesome no doubt but the plot only tells me how impossible it is for us to leave the planet the planet in future(when we haven't yet evolved). I mean that our logic and rationality always stops us from thinking beyond the boundaries(the good point about intuitions). I don't think this species will die on any other planet. If we have to die, we will die here only. I can never imagine humans going to a different planet. It will not happen until we have evolved into some hominid species and that will take about 8000 or 10000 years to happen. Now you ask me why so less time when Homo Sapiens and Neanderthals took a very long time to evo…Read more >
Now when I ask you how did scientists calculate the age of the Universe or earth, you will ponder for a while and the most general answer would be it takes one year for light to travel a light year so that's how they could calculate the age. Now we know the age of Universe is around 13.7 billion years So is this possible for us to calculate the age of the universe so quickly or is it a guess??
No it is not the guess. Let's find out the working behind the calculation of ages.
Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in glaciers that can be counted back 740,000 years. Using the known rate of change in radio-active elements (radiometric dating…

So I came up with some obvious and interesting results one day while playing with numbers:
1/9 = 0.1111111....
2/9 = 0.2222222...
3/9 = 1/3 = 0.3333...
4/9 = 0.444...
5/9 = 0.555...
6/9 = 2/3 = 0.666...
7/9 = 0.7777....
8/9 = 0.888...
9/9 = 1.0000....
10/9 = 10*(1/9) = 1.1111....
11/9 = 10/9 + 1/9 = 1.1111... 0.1111... = 1.2222....
And if you do it furthermore(I don't have time to tell you about the pattern right now), you will get the pattern.

Hello friends, here I am sitting and wondering how to cramm every formula of gravitation and yet I am tempted to look into another interesting article by Michio Kaku on Hyperspace. I am not really old enough to know all the basic concepts and all the physics and theory behind these TOPICS but I do find my interest in things such as Space and universe that's why I just post them right.
I am not a Physicist, not an astronomer, not an astrophysicist but I am a student. Let's Roll.
When I was a child, I used to visit the Japanese Tea Garden in San Francisco. I would spend hours fascinated by the carp, who lived in a very shallow pond just inches beneath the lily pads, just beneath my fingers, totally oblivious to the universe above them.

The following news has been collected from [news.sciencemag.org] You’ve heard of rogue planets, floating through the universe untethered to any solar system. Now meet rogue stars, which drift through space with no galaxy to call home. A new study has come to the startling conclusion that as many as half of all stars in the universe may be rogue, having been ejected from their birthplaces by galaxy collisions or mergers.
Astronomers James Bock of the California Institute of Technology in Pasadena and Asantha Cooray of the University of California, Irvine, didn’t set off to discover a huge population of rogue stars. They wanted to study early galaxies by looking at extragalactic background light, or the EBL. The EBL is essentially all the accu…Read more >
Electrons are elementary particles -- indivisible, unbreakable. But new research suggests the electron's quantum state -- the electron wave function -- can be separated into many parts. That has some strange implications for the theory of quantum mechanics.ew research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell -- or, more accurately, in a helium bubble. Experiments led by Humphrey Maris, professor of physics at Brown, suggest that the quantum state of an electron -- the electron's wave function -- can be shattered into pieces and those pieces can be trapped in tiny bubbles of liquid helium. To be clear, the researchers are not saying that the electron can be broken apart. Electrons …Read more >
Hi everyone, this is draken!
The more curious we are about a topic, the easier it is to learn information about that topic. New research publishing online October 2 in the Cell Press journal Neuron provides insights into what happens in our brains when curiosity is piqued. The findings could help scientists find ways to enhance overall learning and memory in both healthy individuals and those with neurological conditions. "Our findings potentially have far-reaching implications for the public because they reveal insights into how a form of intrinsic motivation -- curiosity -- affects memory. These findings suggest ways to enhance learning in the classroom and other settings," says lead author Dr. Matthias Gruber, of University of California…

The name diaphragm is derived from a flexible disc which comes in contact with a seat at the top of the valve to form a seal. Diaphragm valves are among the most common valves available in the market today. This valve is a flexible element that responds to pressure transmitting the force to open and close. This type of valves is somehow related to pinch valves, but unlike the pinch valves, diaphragm valves use an elastomeric liner in the body to separate the closure element from the flow stream.
Diaphragm valve can either be manual or automated and are mainly used for shutoff purposes in many industries. The older version of this valve could not control and regulate the flow of medium but the latest version has been designed to meet these r…Read more >
Different magnets are used for different purposes. You can get a wide range of verity of magnet in an open market. They differ in shapes and sizes. According to their shapes and sized they are applied in different segments. Though magnets came in many forms, but a Neodymium Block Magnet is always in rectangular shape. Usually they are found in black or dark gray color. Block magnets are composed of alnico, which is however a blend of material like aluminum and nickel and cobalt.
The main feature of Neodymium Block Magnet is that it has both the north and South Pole on both the opposite trimmings end of the Block. Block magnets are used in many science teaching experiments. They are safe to handle. They are widely used for all purposes as it is …Read more >
Shell and Tube Heat Exchangers can be referred to the heat exchangers which are used to transfer heat from one fluid to another or sometimes one medium to another medium. Here the fluid go through a set of titanium tubes, and at the same time another fluid passes all the way through the shell enclosed with the tubes. Thus the titanium heat exchangers are useful for the function application involving high temperature and pressure, or the circumstances where fluid includes particles.
For the recent days industrial application two major types of Shell and Tube Heat Exchangers are used, and those are firstly U- Tube Heat exchangers and secondly Straight Tube Heat exchangers. The U- Tube Heat exchangers make use of a U-shaped tubes fixed, whil…Read more >
There are many variables to be considered when doing this experment. You have to take into consideration: the height of which the object is being dropped from, the size of the object, the mass and density of the object, the object you are using, and much more.
You need to consider the height from which the object is being dropped from because obviously an object that is being dropped from only a few feet will have a much smaller splatter size and impact force then the object that is dropped from a much higher altitued.Read more >
So in conclusion, an object that is bigger and has more mass will create a bigger splatter size/creater then an object with not very much mass. Momentum also plays an important part in how much force the object will have when it hits the ground.Read more >
