Which is the first?

Dinner tonight
Japanese Omlette
Vegetable stir-fry with balsamic honey flavour
Pork balls with aubergine and pepper with soy bean paste sause

Tonight, there's 5th seminar organized by IoP, titled 'Physics at the interface; what biology can learn from physicists.'
It's a combination of biology and physics?....well, it's all about function we understand in physics is already a part of creatures. Especially presenter was talking about liquid crystal and its application in the nature.

Some insects, you know, have metalic coloured skin, and how it can be?....their skin is quite specifically organised so that it reflect similar components of light as metals do. So it appears to be. And actually the structure is similar to the molecule structure of liquid crystal…?

Actually it's amazing that many insects and animals use polarised light to distinguish things from what they want to get. They may know physics already…..for when the sunlight reflects on the surface of water, it'll be polarised in the direction parallel to the surface…..and by which some birds make difference between the land, so that they can easily find water place (lakes, ponds, etc). And some creatures find another sex by polarised light….some find their feed by…..

What's more, the photorecepter(?) is almost same structure and fanction as liquid crystal. It might not be coincidense, but how we can say which is first?....photorecpeter tends to react against specific polarised light and wavelength….

Now we can see lots of application of liquid crystal, especially displaying on the screen, eg digital camera, mobile, calculater, etc…..and also other things must be from the nature.
Which is first? Creatures developed independently and human beings discovered its dominating physics independently?? or creatures has already known, or rather say, they developed so as to match the most effective shape and function, which is result of physics.
There was a physics there, then everything developed following physics…..? Then human being later found its dominant of the world.

Everything seem to be well-designed and well-structured…...It's quite a big mistery….

  1. I think that we only get to see the well designed creatures, because the ones that can't camoflague or can't see polarised light to find their prey, are the ones that die out. So over time all we're left with is the interesting creatures.

    Physics comes along later and explains there techniques, and why there are effective.

    Just a thought!

  2. It may be true. In this world Darwinism seems to dominate, so only creature which got features which match the nature can survive…..
    If the world was different and had more flat areas, there might be a species which has wheels…...? Ha if so, it would be fun~

    um…..physics is the way of understanding of the nature…..and haven't completely comprehend it…....certainly.
