SECRET BEHIND FLASH MIND READER
I figured it out.
Before I reveal how I figured it out, and why it works, let's
review the instructions:
"Choose any two digit number, add together both digits
and then subtract the total from your original number.
When you have the final number look it up on the chart
and find the relevant symbol. Concentrate on the symbol
and when you have it clearly in your mind click on the
crystal ball and it will show you the symbol you are
thinking of"
================================================================
STEP 1: Choose any two digit number
----------------------------------------------------------------
There are lots of those! Numbers 10 to 99. And to emphasize
all those choices we get a graphic filled with wingdings:
Dizzying! All those possibilities. All these numbers the computer
has to figure out when reading your mind! How can it do it?
Can it do it? Is it possible that a computer can read my mind?
================================================================
================================================================
STEP 2: add together both digits and then subtract the total
from your original number.
----------------------------------------------------------------
Oh. Actually it's not going to read the number I thought of. It
wants me to do math first. It's still impressive if it can do it
though, because there are so many possibilities. If I think of
a really hard number that nobody will have thought of, I can
beat this stupid thing and prove it wrong!
================================================================
================================================================
STEP 3: When you have the final number look it up on the chart
and find the relevant symbol. Concentrate on the symbol
and when you have it clearly in your mind click on the
crystal ball and it will show you the symbol you are
thinking of
----------------------------------------------------------------
So you do the math, and the thing works! Aigh! and I chose my
number so carefully!
================================================================
SO HOW DOES IT WORK?
----------------------------------------------------------------
It turns out that for all the possible numbers you can choose,
there are not all that many possible results to the calculation
you are asked to do on the number you choose.
Here's all of the possible numbers, alongside the calculations:
+---------------+-------------------+--------------------+
| ALL TWO | THE DIGITS | THE DIGIT TOTAL |

| 27 | 2 + 7 = 9 | 27 - 9 = 18 |
| 28 | 2 + 8 = 10 | 28 - 10 = 18 |
| 29 | 2 + 9 = 11 | 29 - 11 = 18 |
| 30 | 3 + 0 = 3 | 30 - 3 = 27 |
| 31 | 3 + 1 = 4 | 31 - 4 = 27 |

| 75 | 7 + 5 = 12 | 75 - 12 = 63 |
| 76 | 7 + 6 = 13 | 76 - 13 = 63 |
| 77 | 7 + 7 = 14 | 77 - 14 = 63 |
| 78 | 7 + 8 = 15 | 78 - 15 = 63 |
| 79 | 7 + 9 = 16 | 79 - 16 = 63 |
| 80 | 8 + 0 = 8 | 80 - 8 = 72 |
| 81 | 8 + 1 = 9 | 81 - 9 = 72 |
| 82 | 8 + 2 = 10 | 82 - 10 = 72 |
| 83 | 8 + 3 = 11 | 83 - 11 = 72 |
| 84 | 8 + 4 = 12 | 84 - 12 = 72 |
| 85 | 8 + 5 = 13 | 85 - 13 = 72 |
| 86 | 8 + 6 = 14 | 86 - 14 = 72 |
| 87 | 8 + 7 = 15 | 87 - 15 = 72 |
| 88 | 8 + 8 = 16 | 88 - 16 = 72 |
| 89 | 8 + 9 = 17 | 89 - 17 = 72 |

| 99 | 9 + 9 = 18 | 99 - 18 = 81 |
+---------------+-------------------+--------------------+
We can now see that despite the fact that we get to choose from
numbers 10 to 99, really, there are only 9 possible numbers to
be put on our mind. So while there are lots of symbols provided,
we only have to worry about 9 of them: 9 18 27 36 45 54 63 72 81
And if we look close, we'll find that despite the fact that the
symbols are randomized, there is a peculiar consistency in the
Mind Reader: multiples of 9 always share the same symbol.
Refresh the page and you'll see a new symbol, but 9 and 45 and
81 (and the rest of them) will always share that new symbol.

COMMENT: PSYCHIC THOUGHTS
----------------------------------------------------------------
It irritates me that people believe in psychic phenomena. We so
often attribute strange things to psychic powers. The truth is
that The Flash Mind Reader is a magic trick like all other magic
tricks. It uses misdirection (the many numbers, the randomized
symbols) and hocus pocus (the creepy fade-up of the symbol, the
accompanying sound, vaguely occult wingdings) to get us thinking
about psychic things. The magician only wants you to suspend
your disbelief to fool you. And that's how "The Flash Mind
Reader" works. Magic.
Magic in the sense of hacking with our perceptions and
assumptions. The truth is usually more mundane than we hope.

LOGIC GATES
A logic gate performs a logical operation on one or more logic inputs and produces a single logic output. The logic normally performed is Boolean logic and is most commonly found in digital circuits. Logic gates are primarily implemented electronically using diodes or transistors, but can also be constructed using electromagnetic relays, fluidics, optics, molecules, or even mechanical elements.
In electronic logic, a logic level is represented by a voltage or current, (which depends on the type of electronic logic in use). Each logic gate requires power so that it can source and sink currents to achieve the correct output voltage. In logic circuit diagrams the power is not shown, but in a full electronic schematic, power connections are required.

Applicants for CAT increased
The CAT is out of the bag and has stunned business schools. For the first time in 10 years, the number of applicants for the Common Admission Test (CAT) has taken a plunge. In spite of an extension of 10 days for online registration, a little over 2.41 lakh applicants registered for the exam this year, against 2.7 lakh last year. The CAT exam is the gateway to MBA in Indian Institutes of Management and other top-rung business schools.
The lower number of applicants also caught the CAT Committee unawares. The committee that's holding this year's examination had made a provision for 3 lakh applicants and had kept a buffer ready in case more applied. Now it's searching for answers. "This year, candidates probably noticed the effect on salaries and employment due to economic slowdown," says Satish Deodhar, CAT 2009 Convener and faculty at Indian Institute of Management, Ahmedabad (IIM-A). CAT numbers have consistently registered impressive year-on-year growth of 15-20 per cent in recent years.
Devi Singh, Director, IIM Lucknow, blames unexpected numbers on poor placements. "Since last year's placement scenario wasn't so good, it seems only serious students are going in for MBAs. Earlier, everyone whether a serious candidate or not would write the CAT exam.
While CAT organisers are slightly startled, some industry watchers expected this decline. Says Gautam Puri, Vice Chairman and Co-founder, Career Launcher: "I am surprised the number of applicants managed to touch 2.41 lakh. We were expecting the numbers to be between 2 lakh and 2.25 lakh. Career Launcher, an education services company, offers test preparation to potential MBAs."
Puri attributes his pessimism to poor placement record at B-schools last year. "The feeling among students was that there was no point taking the CAT if it did not guarantee impressive placements, he says.
Another major factor for numbers taking a free fall seems to be CAT turning computer-based. "The moment it became computer-based, students from hinterland backed out, claims Puri. Career Launcher registered higher enrolments for its MBA preparation modules in metros while fewer enrolments were recorded in smaller cities such as Lucknow, Kanpur and Jaipur.
In view of fewer applicants for the CAT, lower-rung institutes that had a harrowing admission and placement season last year have started gathering their act together. One of the steps being considered is reduction in admission fee, according to Puri.
What's in store for the CAT next year? "The numbers will in all probability come back. Or even when they stay at these levels, that's good enough for IIMs. We have only a little more than 2,000 seats on offer," says Devi Singh.
Job market finds its groove
They are hiring again - and at all levels. After almost three consecutive quarters that saw a hiring freeze trend with selective hiring at best, recruiters across key sectors such as healthcare, consumer electronics, automobile and information technology (IT) are actively looking to increase their headcounts. Industry executives say mid-level hiring to hire managers with a few years of experience is the strongest sign yet of a recruitment rebound. Entry-level hires are also up. "Demand for both mid and entry-level recruitments has risen compared to six months ago, indicating companies across various sectors are looking for expansion," said Pramod Thilakan, executive director at the Executive Recruiters' Association. Domestic demand is aiding consumer electronics and automobile companies. Samsung India is recruiting middle and senior marketing professionals, though company officials did not give numbers. Rival LG plans to hire 250 to 300 people in the next six to seven months. "Our focus is on strategic products and we plan to hire experienced professionals for sales and marketing functions," said Yasho V. Verma, HR director at LG Electronics India. Some 30 per cent of Maruti Suzuki's 700 planned hires will be senior and middle recruits and the remainder will be fresh engineers. "Salaries offered are higher than last year's," said S.Y. Siddiqui, managing executive officer, administration. Hyundai has also advertised overseas for recruiting experienced executives.
IT recruitment, hit by a recession in the key US market, is picking up. "Hiring is still not at the peak level of mid-last year but it is building up," Shantanu Banerjee, director, HR, at European IT firm Steria's Indian unit.
