This seems like it would be a bit of a faff. With physical business cards, exchanging them is as simple as moving a card from your pocket into the hand of the person you are giving it to. You can even collect a whole bunch at once and arrange them in front of you to remember everybody’s name at the meeting table. Who really struggles to keep track of physical cards? Insert into holder in alphabetical order when you get back. O(n)

With this there would be at least a couple buttons to mash on the phone, something will almost certainly go wrong with it in the middle of the Big Sales Meeting (sods law), you have to fiddle with your phone instead of looking your new contact in the eye etc etc.

If you are the sort of person that enjoys meticulously tagging mp3 files and has to add every single person they meet to FaceTweetMyspaceLinkedBook then maybe this seems great, but to me this is a solution to a nonexistent problem, that just makes life more difficult.

I took Environmental Science and Evolution and Biodiversity. Both jolly interesting. Expanding the breadth of your knowledge is always good. Your best bet is to pick courses that interest you, that you will enjoy.

Very precise indeed, the reentry vehicles need to be able to change targets in midflight and evade anti-ballistic missile systems. Accuracy is crucial, as you need a much larger nuke to blow something up if your warhead is far way from the target

If you had an unlimited budget you could use space rockets to drop tiny bombs from the other side of the world, but it doesn't really make sense (like killing mosquitos with shotguns). Anyway, the payload is coming down at several kilometers a second, so that 'precise' strike will still destroy a large area from its kinetic energy alone.
