Biomimetic file 184: Surface Tension

How to overcome obstacles with minimal risks

Highlight: “a group of engineers, led by a researcher at the Seoul National University, have just created a machine that can jump on water…the engineers studied the mechanics behind the Water Strider, an insect that can easily jump upwards from a pond. It’s an ability that’s poorly understood in insects in general…The trick, according to an analysis of a high-speed film of Water Striders, is to push down on the water with the maximum velocity that the surface tension can take. The further the insect’s leg pushes down, the greater the surface tension that builds under the leg and the better the upward jump. But if the leg pushes too far, the meniscus—the curved water surface—can’t take it and gives way, allowing the leg to sink…it’s necessary to find the optimal balance: push down hard enough to make maximum use of the surface tension, but not so hard that you rupture it…”

Insight: The water tension analogy is an inspiring business philosophy: The faster an obstacle tries to break the water surface the more difficult it is to go through it; as a matter of fact hitting water at high speeds is similar to trying to go through a concrete wall and a guarantied catastrophic outcome.

Is there something blocking you from moving ahead? If so, perhaps consider a slower well-thought pass-through rather than trying to rush. A slower path is often associated with significantly lesser risks than fast aggressive actions. However, rushing through is always an option and sometimes succeeds (not without risks);

The point to retain here is that if one goes too fast, beyond a certain threshold point, than the failure rate increases sharply…

breakeven-diagramDiagram: Economic models follow similar trends: if you try to go too fast in trying to reach the financial break-even point by pushing aspects such as initial cost benchmark, the sales are likely to collapse. It is all about finding the right balance between time and cost…

The adequate planning of the completion speed of any project (time management) is crucially important in its success rate. It can be really tricky to find the right balance that will keep a project on the track of a successful completion. The reality is that in life some situations are subject to risk taking while avoidance is the norm. Which path would you choose?

What is Biomimetics: the field of gaining inspiration from nature first to solve some of our most difficult challenges. Instead of coming up with our own solutions to a problematic, the odds are that species or natural systems on the planet already offer an ultimate solution. This simple fact is also another strong case to preserve species at all cost as the intellectual heritage contained within or through the study of species is both irreplaceable and invaluable…
