Apollo 14 Astronaut, Dr. Edgar Mitchell presents an elegant scientific explanation for psychic phenomenon - The Quantum Hologram. Based on the latest research in quantum physics, this program brings to the general public information previously known by only a few research scientists in the world. Learn the details of a secret psychic experiment conducted by Mitchell on the Moon during his mission on Apollo 14. Watch as he candidly describes a personal experience of psychic and spiritual transformation that was triggered by his Moon landing aboard Apollo 14 and which led to the discoveries presented in this program. Dr. Edgar Mitchell became the sixth man to walk on the moon and later founded the Institute of Noetic Sciences, an organization dedicated to finding scientific answers to many of humanities great mysteries such as psychic phenomenon.

We all listen to music and watch movies on DVDs. Science fair experiments like this one give you a chance to demonstrate how sounds and images are digitized and stored on disks.
What is Digitizing?
All data can be encoded and stored as a series of bits. A bit is represented as either 0 or 1. A series of 8 bits is called a byte. A byte contains 256 unique values (2 to the power 8 = 256). If your name is Sam, it will be digitized as one unique byte for S, another for A and yet one more for M. So you need 3 bytes to digitize your name.
The Experiment
Using magnets, we are going to a conduct a science fair experiment to see just how much data can be packed into a fixed area and how you can erase it if you want. What you need for this is a few dozen small magnets, one large horseshoe magnet, a ruler, paper and a pencil and a smooth surface to do the experiment on. Ready? Ok, let's start.
Recording th e data
Color the N pole of all the magnets one color. Think of each magnet as a bit and separate them into groups of 8 (8 bits for each letter). Lay one group on the sheet of paper in a horizontal line, about 2 inches from each other with the N pole pointing to the left. Make a similar line of the next 8 magnets about 2 inches below the first and do the same for the third group of magnets The area covered by the magnets is the recording surface where you have recorded the letters S, A and M.But suppose you want to record more data in the same area? How much more can you fit in?
To fit in more data you will have to move the magnets closer to give yourself more space. Start doing that. You will reach appoint where the magnets get attracted to each other and come together. The carefully laid out lines of information are now a mess. It's a jumble that doesn't make sense and the information is lost. The maximum number of lines of magnets you can place on the paper is your maximum data storage capacity.This is what happens of you try to store too much material in a limited space and is why a DVD will have a fixed storage capacity and will not accept information beyond that point - it will get scrambled.
Erasing Data
Set up the 3 lines of magnets in the same way. Move the horseshoe magnet over the lines from a height of about six inches and slowly keep lowering the horseshoe magnet. You will reach a point where the horseshoe magnet starts pulling the bar magnets as it moves over them. The neat lines are disturbed.This is how erasing happens. The bits are moved from their places and the information is gone. When new information is recorded, it will be like the lines being made again but with a differing sequence because the information is different. This is one of the most basic science fair experiments you can do, but if you know the theory behind it, you will make a great impression on the judges.

I want to major in psychology and I have the options of choosing bachelor of science and bachelor of art. What's the difference? Best answer for Whats the difference between bachlor of science and art?:
Answer by ♥
At the universities in my state, a B.S. degree will require only 2 semesters of a foreign language but the B.A. will require 4 semesters. You should go to the degree plan section on your university's website and compare the B.S. and B.A. You might have a higher math or hard science requirement for the B.S.
Answer by Chris
There is no consistent answer as each college does this differently. For instance under NY law a BA must have 90 credits of liberal arts and a BS must have 60. That is the only actual difference. Many colleges use BA for degrees that are more general and BS degrees for a more focused degree but not all colleges do this.
Answer by William C
Bach of arts, you will have a major that is not in the science arena. An example is your major might be economics or marketing Bach of science, your major might be biology or entomology You will have two years of taking your basic courses and that will give you time to select which bach you want. I would not go for the psyc major unless you are planning to get your masters degree. There is very little demand for psyc majors. It may sound like a good degree but it really is not. Very few grads get a major in what they initially planned.
Answer by DaniBaje
As Chris wrote it depends on your university. In terms of the BA and BS in Psychology, some BS programs contain more math and science classes than BA programs; whereas BA programs contain more humanities related classes. However, this is NOT always the case. You will need to compare the requirements for each degree. Neither option is better as either option will allow you to go onto grad school
