Does the word rishathra still exist?

What about this one: both general relativity and quantum mechanics are remarkably accurate in their respective areas (large masses and distances for GR, small ones for QM). One would expect some generalized theory that simplifies to GR for large masses/distances, to QM for small ones, and to Newtonian mechanics for intermediate ones. However, GR and QM are fundamentally incompatible. (Hint: time as inextricable part of spacetime in the one case vs time as a parameter, space as an operator in the other.)

Actually, using your mobile phone to authenticate a transaction used to be a good idea -- back when phones (and SMS/texting) provided a separate communication channel from the internet, so even if your computer was compromised, you had the chance notice something was amiss. With today's smartphones, there is no real separation anymore, because an attacker just needs to compromise texting and banking apps (or the web browser) on the phone; or on the desktop and the phone, but that is easy because the phone is managed from the desktop.

Apparently, many people nowadays you Google to find their favourite sites. Even if they do know the URL. Like this: http://google.com?q=slashdot.org.
