Physics allows practical applications of mathematics, whether using sine/cosine to explain wave motion or complex calculation of celestial objects, like planetary orbits. Yet it still cannot explain quantum mechanics, i.e. interactions of subatomic particles because there the general laws of physics do not work. So basically it just comes down to how much of physics knowledge that humanity has obtained up to now really explains the universe - and it seems there are still vasts gaps in science that still needs to be filled.

FYI quantum (field) theory is the best and the most accurate physical theory in existence today.

wonderful link ... the scale size is amazing to see how much we have learned about the universe, and how much learning still remains

very interesting article ... thanks for sharing

I started playing the original Civilization (floppy disk version) back in middle school. Gradually went on to play other versions that came out later (including the Alpha Centauri version). I consider it one of the best strategy and overall enjoyable game I've ever played.

Zebra is a great metaphor for the type of companies investors should be funding. What we continue to forget is that technology is supported to help build better societies and communities, and not the other way around, where we continue to get more dependent on it (even addicted to it). Look everywhere people are checking every 5 minutes to see what's on social media. People are more than happy to see and contribute on videos of cats and other meaningless junk, but not on meaningful literature.

very nice article. Uplifting. So many times people feel otherwise because they are compelled to think this way ...

This is a well written article. I agree that this problem is growing, due to less social interaction and more reliance on social media tools and apps. This is not good for society

It's a great search engine, and gettig better with time ..

Very nice article. It is nice to see photoshop-like capabilities added to web applications. Although, it seems a pain to use with various platforms, like Java, .NET ... image manipulation is needed depending on what device or connection speed the requester might be using. I would like non-camera pics to be vector based, to allow dynamic resizing. And camera photos should use this capabilities, along with a small link provided to download full quality photo, if needed. But these image manipulation capabilities should be part of a framework so that it is easier to use and update. After all, every page is littered with images, however, there is so little we can do with them right now. Good approach though to start of with ...

Very nice article. This statement sums it all "The problem: “game changing” technologies cannot do their magic if the players and the playing fields remain the same." Take tennis. Titanium and other lightweight materials along with other customization of racquets allowed players to drastically improve their shot selection. However, only the ones that combined this with their mental and physical fitness reaped greatest benefits. Same goes for the technologies. Only when everyone is aware of their potential benefits and is trained properly to use them, they will not yield their maximum benefit.
