Reynolds Number

This video does an outstanding job of making the Reynolds Number meaningful. More about the use of the Reynolds Number in scale model testing in future posts!

Pop! The Science of Bubbles

In this BBC presentation, Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science. From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it’s the future of ship design or innovative new forms of medical treatment, bubbles play a vital role.

It’s a long video, but well worth the time. Pop your self some popcorn. Grab a bottle of water. Settle back to be enthralled by —— bubbles

Who Knew: Penguins

One of the most impressive things about penguins – and puffins – is the way they rocket out of the water to land on the ice. Not only do they stick the landing, they come out of the water with enough momentum to gain a foothold.

In this video, Helen Czerski – physicist and oceanographer based at the Institute for Sound and Vibration Research at the University of Southampton – explains the role that fluid dynamic principles play in this amazing penguin ability.

Ueli Gegenschatz: Extreme Wingsuit Flying

Ueli Gegenschatz takes everything we know about aerodynamics and puts it all into a series of brilliant extreme sports experiences in the pursuit of his dream of human flight. You can view this video and think about lift, drag, thrust, and weight, but chances are you’ll be too busy wishing you were there with him!

Says Gegenschatz: “I believe this is probably the closest possibility to come to the dream of being able to fly.”

TED Talks

about_tedTED Talks are a way to share Ideas Worth Sharing. It all started in 1984 as a one-time conference to bring people from the technology, entertainment, and design sectors together. Since then, the TED nonprofit has evolved into an organization with two annual conferences, a site to host the videos, and a number of related activities.

TED Talks must be 18 minutes or less. The speakers are invited to make their presentations because they are considered to be fascinating thinkers. There are more than 1,500 TED talks now available for viewing. All of the talks can be viewed for free, and more are added each week.

It’s hard not to be excited at the thought of thought-provoking presentations by respected thinkers. Because of that, TED Talks are a part of this blog. I hope you enjoy them and are intrigued by the ideas they present.

Wright Brothers 1901 Glider

The Wright brothers were off and running with their ideas for manned flight. The camber of their wing matched that of the wings used by Lilienthal. Unfortunately, Lilienthal’s figures were incorrect due to an error in the Smeaton coefficient. To get around this, the Wright’s came up with a way to modify the curvature of the wing.

The poor results from these tests led the brothers to undertake wind tunnel tests of their own.

Wright Brothers Wing Warping Test 1899

The Wright brothers were able to control the flight of their manned aircraft through the use of wing warping. Far more sophisticated than Lilienthal’s use of shifting body weight, wing warping allowed aerodynamic control of the wing.

The Wright brothers were meticulous in their research. This research, along with their can-do and innovative approach to flight, resulted in their first successful, controlled, heavier than air flight at Kitty Hawk.
