[phys.org] Why water splashes—new theory reveals secrets

post #1 of 31
Thread Starter 
Quote:
Dr James Sprittles from the Mathematics Institute has created a new theory to explain exactly what happens - in the tiny space between a drop of water and a surface - to cause a splash.
Quote:
Dr Sprittles has established exactly what happens to this miniscule layer of air during the super-fast action by developing a new theory, capturing its microscopic dynamics – factoring in different physical conditions, such as liquid viscosity and air pressure, to predict whether splashes will occur or not.
Quote:
Understanding the conditions that cause splashing enables researchers to find out how to prevent it – leading to potential breakthroughs in various fields.

It's quite astonishing to see how the forefronts of technology can sometimes be affected by such simple things.

If memory serves, Einstein came up with the concept of the theory of relativity by observing a train.

Interesting article! thanks for sharing.

Appreciated. I haven't been here in a while and the current headlines I faced seem to have headed towards the gloom of the industries' legal battles. While things like this need to be discussed, I try to remind people there's other interesting things going on.

In truth I am somewhat surprised that a more thorough investigation along these lines didn't reach the surface back when that new hydrophobic spray 3M had developed was all the rage. I suppose function was more important than the mechanics of it.

But anyways, in this case, I am somewhat a follower of materials science, ever since graphene became popular. It's not been so often that fluid dynamics is the focus of research in terms of usable properties. I'm hoping this is some kind of breakthrough in principle that can help make liquids appealing to the nano work.

I'm in the wrong line of work. I should do useless studies, call it science and collect a paycheck. This is about as dumb as studying where headaches come from only to end with "your head." Someone please explain why this is remotely news worthy. With all the real problems in the world this is what they focus on? Really?

I wonder how much money went into the great question of why water splashes? Ugh... Now that we know, do we have the cure for cancer?

Give us a reason as to why it's useless, and we'll give you reasons at to why its not.

This makes me dream of a future where i won't get gatorade on myself when it splashes up after a gulp. tongue.gif

Or better yet, one day, I might be able to wear a white shirt to eat pho.
