"To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation — shining intense laser beams onto the material to stimulate the molecules in a very small focus point.""
Depends on what you mean by "pattern", of course, but pi is conjectured to be normal, which would exclude many sorts of patterns. It's not proven, though.
And I suppose she carries your balls around in her purse?
Also, you misspelled licenses. I'm usually the guy that people point out grammatical errors to, rather than visa versa. But, still, if you are going to offer advice about a subject, it helps your creditability to actually spell it correctly. Or at least use a web browser with integrated spell checking. Again, the point of posting was not nitpicking, but clarifying as posts similar to your last one have led to quite a bit of misinformation about the GPL license.
Since we've already gone off the topic anyway and getting modded up for it, I might as well point out a couple of things in your post.
Licence can be spelt with a c. In fact it is spelt with a c in British English where I believe the language originated from.
But well done for being a bitch about it.
By the way, were you meant to say too instead of to in that sentence? Saying to doesn't make much sense to me
For being a guy that usually point out peoples grammatical errors and spelling mistakes, you really aren't that good writing yourself.
