A great interactive map from Gmaps of the swine flu pandemic.

Card Lamp Folds Flat on Desk to Keep Desk Clean

042809_rg_toshiba_card_lamp_01.jpgIf you are like me, your desk must be a mess. Mine is overflowing with paper and books, computers and envelopes all over the place. More space on your desk leaves room for even more papers. The Card lamp is a new LED lamp that totally folds flat, making space for more clutter. Or if you are really well organized, it leaves you more space to work.

OLED Lamps: Sleek and Thin

042809_rg_oled_lamps_01.jpgA lot of people are talking about OLEDs, but this is the first time I’ve actually considered that OLEDs can be used to actually light stuff up, just like LEDs. The beauty of OLED displays is that they are incredibly thin and luminescent, kind of like when LED displays first appeared. Now that LED is becoming more prevalent, a cleaner and greener alternative is also appearing in the form of OLEDs.

Stardust Light Furniture: Like it or Hate it

If you had furniture that could light-up like a spaceship, would that make you happy? Is light something that could be used in furniture without being too awkward? Those are the questions that the Stardust furniture line from Meritalia explores. It’s hard to judge your feelings for something this bold. It’s easy to dismiss it and to say that it is tasteless, but most provocative items will evoke feelings like this.

Mini Workstation: Fits in Rooms of Any Size

042709_rg_imove_workstation_01.jpgHave you ever found yourself wishing you had a compact workstation for the garden, the living room, or your room? Wonder no more, because the iMove is the perfect solution to your workstation related blues. The iMove is a tiny workstation what will fit all laptops. It comes complete with an adjustable table and a seat, which neatly slides underneath. It’s almost like a stool. It fits in any rooms of any size, even your closet!

Knock Knock Math Joke

-Knock knock!
-Who’s there?
-3 period.
-3 period?
-3 PERIOD IMPLIES CHAOS!

Seemed a lot funnier in my head after 27 hours awake.

Or more like 32 hours no sleep.

Then 2 hours sleep.

Then 6 hours no sleep.

Getting really loony.

Update: I got about 10 hours sleep last night and woke up refreshed.

Zonked Out

I’ve been up since 9AM on Sunday. I managed to sleep from 2:30PM till 5PM. I had an important exam this morning. It went well, but it’s left be a bit knackered.

I plan on staying up another half hour to complete my work and then hit the sack. Tomorrow I can sleep in, but I’ve got another exam on Thursday. I’ve cleared my schedule on Thursday, so I should be able to study hard for that exam as well. I’ve been using Red Bull on this end of semester and I have to say that it works well when used in moderation.

My exam went pretty well. Otherwise than obsessing on the Li-Yorke Theorem, I’m sure that I did pretty well, a lot better than the last exam. Li-Yorke is really useful for demonstrating that a function is chaotic. All that you need to find is a 3-periodic point. Once you have that, it implies that f is chaotic. It’s a lot easier than showing that all periodic points are dense, transitive and that f is sensitive to initial conditions.

Li-Yorke Theorem

After my exam, I kept repeating:

Period three equals chaos.

over and over again in my head. I couldn’t stop.

The Li-Yorke Theorem is a special case of the Sharkovskii Theorem.
