I'm a normal man in love with every good thing. Egyptian, Engineer, love reading, technology, computing and horseback riding..

Cave Inn Ryan Deboodt, National Geographic Your Shot
"After two days of trekking and caving, we reached the first camp inside Hang Son Doong [Mountain River Cave], the world’s largest cave,” writes Your Shot contributor Ryan Deboodt. “The entire way, I was in awe of the scene unfolding in front of me. The atmosphere created by the clouds entering the cave from the first doline (opening in the cave ceiling) was surreal. I couldn’t get over the fact that we would be camping at this most unique location and wanted to capture the feeling of having this at your doorstep.”

A new transparent, bioinspired coating makes ordinary glass tough, self-cleaning and incredibly slippery, a team from the Wyss Institute for Biologically Inspired Engineering at Harvard University and Harvard School of Engineering and Applied Sciences (SEAS) reported online in the July 31 edition of Nature Communications.
The new coating could be used to create durable, scratch-resistant lenses for eyeglasses, self-cleaning windows, improved solar panels and new medical diagnostic devices, said principal investigator Joanna Aizenberg, Ph.D., who is a Core Faculty Member at the Wyss Institute, Amy Smith Berylson Professor of Materials Science at SEAS, and a Professor of Chemistry and Chemical Biology.
The new coating builds on an award-winning technology that Aizenberg and her team pioneered called Slippery Liquid-Infused Porous Surfaces (SLIPS)—the slipperiest synthetic surface known. The new coating is equally slippery, but much more durable and fully transparent. Together these advances solve longstanding challenges in creating commercially useful materials that repel almost everything.
SLIPS was inspired by the slick strategy of the carnivorous pitcher plant, which lures insects onto the ultraslippery surface of its leaves, where they slide to their doom. Unlike earlier water-repelling materials, SLIPS repels oil and sticky liquids like honey, and it resists ice formation and bacterial biofilms as well.
While SLIPS was an important advance, it was also “a proof of principle” – the first step toward a commercially valuable technology, said lead author Nicolas Vogel, Ph.D., a postdoctoral fellow in applied physics at Harvard SEAS.
the honeycomb structure of the SLIPS coating on the glass slides confers unmatched mechanical robustness. It withstood damage and remained slippery after various treatments that can scratch and compromise ordinary glass surfaces and other popular liquid-repellent materials, including touching, peeling off a piece of tape, wiping with a tissue.
Skydiver Survives 24 Mile Drop
Felix Baumgartner stood alone at the edge of space, poised in the open doorway of a capsule suspended above Earth and wondering if he would make it back alive. Twenty four miles below him, millions of people were right there with him, watching on the Internet and marveling at the wonder of the moment.
A second later, he stepped off the capsule and barreled toward the New Mexico desert as a tiny white speck against a darkly-tinted sky. Millions watched him breathlessly as he shattered the sound barrier and then landed safely about nine minutes later, becoming the world’s first supersonic skydiver.

Amazing, would love if I tried it.
“Acquire knowledge, you will be known by it. Perform deeds and you will be the men of knowledge. A time will come after you when nine out of ten truths will be rejected. None, but the oft-repeating penitent will be safe. They are the leaders of guidance, lights of knowledge, not hasty or verbose.”
— Ali ibn Abi Talib (radiAllaahu anhu)
