Top Ten Physics Experiments Ever

02/14/2006 5:49 PM

Robert P. Crease, a member of the philosophy department at the State University of New York at Stony Brook and the historian at Brookhaven National Laboratory, recently asked physicists to nominate the most beautiful experiment of all time.

The results were:

1. Double-slit electron diffraction - Showed Electrons have wavelike properties.
2. Galileo's Tower of Pisa Experiment - Showed that objects fall at the same rate, regardless of mass.
3. Millikan's oil-drop experiment - Determined the fundamental charge unit, the charge of an electron.
4. Newton's Prism - Showed White light made up of colored light.
5. Young's Interference Experiment - Showed that light has wavelike properties.
6. Cavendish's torsion-bar experiment - Measured the value of the gravitational constant (G).
7. Eratosthenes' Experiment - Measured the circumference of the earth, in 276 BC.
8. Galileo's Inclined Plane Experiment - Demonstrated that distance travelled by a ball rolling down an incline plane is proportional to the square of the time.
9. Rutherford's discovery of the nucleus- Discovered atoms consist of a small nucleus surrounded by electrons.
10. Foucault's Pendulum - Demonstrated that the Earth rotates.

I think the pendulum was pretty cool. I wasn't aware of the Galileo one, I guess that really set the table for Newton.

Very Nice Idea to Post these

"I think the pendulum was pretty cool. I wasn't aware of the Galileo one, I guess that really set the table for Newton." And we all thought it was the apple? Nice post, Roger

Rutherford

I have to go with the formulation of the atomic model. His papers are definitely worth reading.

Overlooked experiments

02/15/2006 11:26 AM

Some notable experiments overlooked by the physicists:

1. Victor Frankenstein's re-animation of necrotic human tissue about 1818. While the experiment itself was beautiful and extraordinary, the result was monstrous.

2. Fester Addams discovery of the human oral cavity electrical power source and experimental applications (light bulb), 1965. However, some claim that his experiment was flawed and accused him of swallowing a series of D-cell batteries immediately prior to conducting his experiment. There were many other charges, some positive, some negative. I think his work was simply brilliant!

3. Practical experiments utilizing the principles of linear translation by revolution of round objects (Invention of the Wheel) by Nebugamesh the Sumerian of Mesopotamia around 5500 BC. Greatest invention until sliced bread! (1928)

4. Artificial ignition of combustible materials (non-natural fire-starting), generally credited to Og of the mountain people, circa 98,000 BC who experimentally impacted various mineral objects to created sparks which ignited indigenous organic materials.

Can anyone think of any more?

You are a heretic! Everyone knows it was Lothar of the Hill people who discovered fire. Og stole it from him.

I am sorry, Mr. Elvis. May I call you Tiny? That is a common misconception. While Lothar did carry out experiments in sustained combustion based on naturally occurring fire (lightning, lava, etc.), it was Og who succeeded in artificially creating and sustaining combustion. Getting fire from lightning or lava is so simple, even a Caveman can do that!

While Lothar or Og might have been the first Homo Sapiens to use/harness fire, their intellect pales in comparison to the mighty Neanderthals who pioneered the use of it. A humbling thought considering that all of us are probably related to Og and Lothar in some way. Since the Neanderthal who made this monumental achievement is lost to history, this event didn't make the list.

Also, we at CR4 were unable to pin the exact time of the following historical events, thus they didn't make the list:
1. Invention of the Wheel
2. Invention of Agriculture
3. Invention of Buildings
4. Invention of the Double Stuffed Oreo
