DAY 2: Breaking Ice

Finally kicked off with the project long dreamt. Automated locking system, cuz we're too lazy to go up to the door to open it.

The first thing I had on my mind was to use an electromagnet as the armature to lock and unlock. And electromagnets do NOT work on AC... So, I had this brilliantly stupid idea of using the phone adapter...

R.I.P moto

...to substitute a battery. So what I did was...

split ends =] :D

...this!.. :D So, I plug the adapter into the socket. Control!... Where's the control for the experiment?!.. After a bit of scrounging through a pile of crap, I find this bulb, rated 250 V 10 W!.. I know this is not even close to a sensible choice to check for a 375 mA output!.. Why not just give a try?... And the outcome?...:D 

EPIC!

So, after some more of scrounging, I now find a clock. An alarm clock.

Controls(the pen, the papers and the pad excluded!).

I pluck the batteries out and connect the terminals. :| No surprise. No effect. :|

Frustrated, I try touching the terminals... :D :| No surprise, no effect again!

And short circuiting?... FAIL... 

Can't stand this anymore. SLEEP... zz z z zz zzz zzz

DAY 1: Polarization of the Light

QUBITS: Quantum Computing :\ (nerdy huh?)

Keeping track of my progress...

One of the basic kinds qubits are displayed by polarizing photons. So, I just started off by making sure I remember the basic polarizing stuff(which I have had done with the last year)...

Do you remember the wave equations?...

Yes I do!... =] And most of the basic stuff on polarization.
Lemme just skip to the notes on Circular Polarization.

So, this kind of polarization, as is pretty obvious, occurs when two linearly polarized lights superposition themselves to form a waveform, where the angle keeps varying, making it look like, the Electric field vector pointing in circles. 

The directions pointer at the origin is the direction of the E Field at that very moment.

The elliptical polarization occurs when the amplitudes of the two super imposing waves are different, or the  phase lag is other than pi/2.

Most general case occurs when the amplitude, phase lag, and the frequency are all arbitrary. 

Up tomorrow: Polarization of photons
