How Well Can Your Eyes Perceive Color?

Calling all artists, critics, creatives of any kind, oracles, crystal gazers, nature fiends, chefs, fashionistas — basically, anyone who enjoys color on a daily basis. Sure, you appreciate a deep azure or a crisp cerulean — but can you decipher between the two?

It’s time to put your peepers to the test. We stumbled across a test on Social Eyes, that, through a quick series of exercises, assesses just how well your brain digests the spectral compositions of light reflected by objects.

So, do you dare to put your vision to the test? You might not be colorblind (a person experiencing colorblindness may only be able to distinguish up to 20 different hues in their daily lives), but you could be color-deficient (meaning, you are seeing less than the 100 or more hues that a normal-sighted person can see).

Well, you can take Social Eyes’ quiz HERE and let us know how you fared in the comments. Or, you can try our unofficial, unscientific quiz below. Can you beat a HuffPost Arts editor at a game of Guess Which Color Doesn’t Belong? You can sure as hell try. Differentiate at least 10 of the colors below and you can crown yourself a pigment master.

Discovering Propellantless Propulsion (1)

For someone who is determined to get propellantless propulsion off the ground, I worry that there isn’t enough experimental research to make propellantless propulsion a reality sooner rather than later. And if you think that propellantless propulsion will not be big science one day, take a look at Airbus’s Sept 17 2015, US Patent, US 2015/0260168 A1. (Begs the question, how many years of quiet research did they put in before reaching a patent worthy application?) That is, any major aerospace company that is ignoring propellantless propulsion will be blindsided.

The discovery of physics is a deliberately orchestrated endeavor that requires forethought, planning and above all the willingness to face the unknown. And occasionally we hit jackpot with accidental or serendipitous findings only because we were searching with an open mind.

Some years ago, Prof. Tajmar and I were Co-Chairs of the Space, Propulsion, Energy Sciences, International Forum (SPESIF 2010, 2011, 2012) A03.1. Theories, Models & Concepts: Frontiers in Propulsion Science. We had different approaches to physics. He was very meticulous about experimental methods. Getting it right required examining all sources of experimental errors. Having accounted for the errors you could be sure of what you were observing. And then using theory to guide the experiments.

If the observations would not confirm the theoretical underpinnings of legacy physics, it could suggest new physics. However, the physics community frowns on new physics, and every attempt is made to explain new phenomena with legacy physics, even if it gets convoluted. If it cannot be explained with legacy physics, then the experiments are defunded and the physics community moves on to something else. Antigravity or gravity modification is a good example. At least since the 1960s many different organizations have repeatedly failed —> Read More
