• Game No. 1

Study the circles below.

Work out what number should replace the question

mark.

Hit

4 * 5 + 3* 6 = 38

8 * 4 + 3 * 5 = 47

• GameNo. 2

 Draw a square made up of dots like this one on

 Now, without lifting the pencil from the page,

draw no more than four straight lines which will

cross through all nine dots

• Hint

One line can go out of the paper

• Solution

• Lessons Learned

• Do not discard small details

• You might think that things are

very complicated but with

little guide it becomes very easy

• Video Part

1965 prediction by Intel

cofounder Gordon Moore:

The number of transistors

that can be built on the same

size piece of silicon will

double every 18 months

The most profound

technologies are those

that disappear. They

weave themselves into

the fabric of everyday life

until they are

indistinguishable from it.
