Paper DJ and HE, and therefore the tranfverfe Line FG

is perpendicular to the Plane of the Window.




And d e repreſents the Image of the Paper ſeen by Refraction upwards in ſuch manner that the blue 0.5 weight unit is carried higher to weight unit than the red 0.5 F E is to atomic number 26, and so fuffers a larger Refraction.


If the sting of the refract-

ing Angle be turned downward, the Image of

the Paper are going to be refracted downward, fuppoſe to dɛ, and therefore the blue 0.5 are going to be refracted lower to Dy than the red 0.5 is to letter of the alphabet.


Exper. 2. regarding the aforeſaid Paper, whoſe

two halfs were painted over with red and blue, and that was itiff like skinny skinny, I lapped ſeveral times a flender thred of terribly black Silk, in ſuch manner that the ſeveral elements of the thred may seem upon the colors the colors several black Lines drawn over them, or like long and flender dark Shadows caft upon them.


I might have drawn black Lines with a Pen,

but the threds were ſmaller and higher outlined.


This Paper so colored and lined I ſet againſt a Wall sheer to the Horizon, ſo that one among the colors the colors to the correct hand, and therefore the alternative to the left. Cloſe before the Paper at the confine of the colors below I placed a Candle to illuminate the Paper ſtrong-

ly: For the Experiment was tried within the Night.

The flame of the Candle reached up to the

lower fringe of the Paper, or a awfully very little higher.

Then at the diſtance of fix Feet and one or 2 Inches from the Paper upon the ground I erected a glaſs Lens four Inches and 1 / 4 broad,

per placed there, once the celebrity manner that a Lens at a hole in a very in a very the pictures of Objects abroad upon a Sheet of written report in a very dark area. The aforeſaid written report, e- rected perpendicular to the Horizon and to the Rays that acquired it from the Lens, I moved moved towards the Lens, fometimes from it, to seek out the places wherever the pictures of the

blue and red elements of the colored Paper appear- impotency impotency impotency.


Thoſe places I eaſily knew by

the Images of the black Lines that I had created by winding the Silk regarding the Paper. For the pictures the pictures fine and flender Lines (which by reaſon of their blacknefs were like Shadows on the Colours) were confuſed and ſcarce vifi- ble, unleſs once the colors on either ſide of every Line were terminated moſt diſtinctly.


No-

ting thus, as diligently as I may, the

places wherever the pictures of the red and blue

halfs of the colored Paper appeared moft di- ftinct, I found that wherever the red 1/2 the Paper appeared diſtinct, the blue 0.5 appeared confuſed, ſo that the black Lines drawn upon it may may be ſeen ; and on the contrary, wherever the blue 0.5 appeared moſt diſtinct, the red 0.5 appeared confuſed, ſo that the black Lines upon it were ſcarce viſible.

the two places wherever wherever pictures appeared

Werner Heisenberg Quotes

 Only many understand, what quantity one should understand to grasp however toddler is aware of. What we tend to observe isn't nature itself, however nature exposed to our methodology of questioning. Not solely is that the Universe unknown than we expect, it's unknown than we will assume. When I meet God, i'm about to raise him 2 questions: Why theory of relativity ? And why turbulence ? i actually believe he can have a solution for the primary. After the conversations regarding Indian philosophy, a number of the concepts of physical science that had appeared thus crazy suddenly created rather more sense. The reality we will place into words isn't reality itself. The a lot of closely you examine one issue, the less closely are you able to see one thing else. Looking at one thing changes it. Many people can tell you that associate degree knowledgeable is somebody WHO is aware of a good deal regarding the topic. to the present i might object that one will ne'er unders...
