THE INVERTED RETINA

-


      The human eye contains a RETINA –a membrane with approximately 120 million cells called PHOTORECEPTORS, which absorb light rays and convert them into electric signals. Your brain interprets these signals as visual images. Evolutionists have contended that where the retina is placed in the eyes of vertebrates, creatures with a backbone, proves that the eye had no designer.
      The retina of VERTEBRATES is inverted, placing the photoreceptors at the back of the retina. To reach them, light must pass through several layers of cells. According to evolutionary biologist Kenneth Miller, this arrangement SCATTERS the light, making our vision less detailed than it might be.
       Evolutionists thus claim that the inverted retina is evidence of poor design –really, no design. One scientist even described it as a functionally stupid upside-down orientation. However, further research reveals that the photoreceptors of the inverted retina are ideally placed next to the pigment epithelium –a cell layer that provides oxygen and nutrients vital to keen sight. If the pigment epithelium tissue were placed IN FRONT of the retina, sight would be seriously compromised.
      The inverted retina is especially advantageous for vertebrates with small eyes. Between the lens of the eye and the photoreceptors, there must be a certain distance to get a sharp image. Having this space filled with nerve cells means an important saving of space for vertebrates.
      Additionally, with the nerve cells of the retina tightly packed and close to the photoreceptors, analysis of visual information is fast and reliable.

PLASTIC SURGERY; PROS AND CONS

-
“Prior to my nose operation, I suffered a lot because of teasing. I did not want a nose that was special, just one that suited me. I am very happy with the result, and I would do same thing all over again.”-Elea.” “Why should I submit to standardized ideas of good looks? With surgically altered body parts. I would feel like fake money. Not genuine.”-Matthew. “Everyone must decide for himself or herself. It is very difficult for someone else to judge.”-Imma “Whoever is prettier than I am must be wearing makeup.” In Germany, that humorous saying has long served as a sort of defense for people who worry that their looks are less than perfect. In some lands nowadays, though, the saying might well be updated to: “Whoever is prettier than I am must have gone under knife.” Indeed, cosmetic surgery is becoming commonplace. “The days are over when cosmetic surgery was reserved for the rich,” reports the Swiss newspaper Neue Zurcher Zeitung, adding: “Two trends have emerged: More and more me

THE HUMAN PERFECT BODY

-
OUR BODY: THE PERFECT MACHINE - When you reflect on the remarkable abilities of various animals, do you sometimes feel a twinge of envy? Perhaps you wish that you could soar like an albatross, swim like a dolphin, see like an eagle, or run like a cheetah. Yes, animals have some amazing abilities. But so do we! Indeed, the human body has been described as the perfect machine. Of course, we are much more than a machine. We have creativity, curiosity, imagination, and ingenuity –qualities that move us to devise machines that enable us to do virtually anything we set our minds to. https://mysticrealityfacts.blogspot.com/2014/12/the-magic-in-your-fingers.html We can fly, even beyond the speed of sound; navigate above or below the surface of vast oceans; gaze some 14 billion light-years into space; peer into the living cell; and design medicines, therapies, and technologies that help us diagnose and treat diseases. Even with little or no external assista

RUSSIAN BLINI

-
RUSSIAN BLINI The French have their CREPES, the Scots their BANNOCK, and the Americans their FLAPJACKS. So it comes as no surprise that Russians have their own version of the PANCAKE –the BLIN, which is a staple with a long history. The ancient Slavs used blini for food sacrifices in their pagan rituals and saw in blini an appropriate symbol of round, warm, golden sun. Women who had recently given birth were fed blini. These were also served at weddings and at funerals, so they figured in peoples’ lives from birth to death. Russians today usually make blini with wheat flour, but other flours can also be used. RECIPE FOR BUCKWHEAT BLINI INGREDIENTS 120 grams buckwheat flour 120 grams wheat flour 20 grams butter, melted 2 eggs 720 milliliters or so of milk 30 grams sugar Pinch of salt PREPARATION: Mix buckwheat flour with 240 milliliters of milk. Heat another 240 milliliters of milk, and add it to the batter,
