The purpose of this course is to learn to think with data

Not to study

Not to teach

But to learn

To learn is to change our behavior rules

We think different, we act different

We think with two strategies:

• analytical
• automatic

So learning has to be in two stages

We learn what we do, not what we study

Like riding a bike

Can you learn to dance only reading Wikipedia?

Some theory, a lot of practice

Failure is expected. We learn from failure. Try judo

Not always. Kids learn easily.

We have difficult learning new things because we have to unlearn old habits.

So we will need to make an extra effort

According to cognitive research, there are three main ways of remembering

• A few people remembers what they see
• Some people remembers what they listen
• Most people remembers what they do
  • Kinesthetic sense: body position
  • “The pen is mightier than the keyboard”

Moreover logic is tightly connected with language

It’s easy to get distracted,
specially when we don’t like the task

We learn by getting out of or “comfort zone”

Learning is uncomfortable, even annoying

We have to push ourselves to focus

• set a timer for 25 minutes
• force yourself to focus on that period
• no email, no Facebook, no toilet, no coffee/cigarettes
• in case of interruption, restart from zero
• when the bell rings STOP working for 5 minutes
• every 3 Pomodoros, take a 20 min break

We will use this technique in this course

We have roughly three stages of memory

• very short term memory (seconds)
• medium term memory (hours)
• long term memory (years)

Transition between medium and long term memory happens when we sleep (and dream)

That is why we have 2 sessions per week

Attend to classes regularly (always!)

Bring a notebook and a pen
Handwrite what we speak, and your own questions
Summarize at the end of the class (Cornell Method)

Speak with your classmates

Sleep well (but not during the class)

For every complex problem there is always a simple, direct and wrong solution

We may want an easy way, but that is a bad idea

1. We learn better when there is some desired difficulty
2. If it is easy, a robot can do it
3. Nobody is proud of doing something easy

Be honest

Remember: one byte = one letter

Computer Science people thinks in Bytes

A number between 0 and 255

That is, 256 combinations. Why?

Your undergrad study is 4 years, which we can split in two groups: Old and Young

We can represent each group with 1 and 0

In each group we can split again in two: Begin and End

We can also represent them with 1 and 0

The we have two semesters: Spring and Fall

Each time we split in half, we multiply by two the combinations’ number

This is the reason why we use powers of 2

Learn these:

In Science we use the decimal system

In Computing this is usually replaced by 2¹⁰=1024

Similar but not the same

The difference between kilo and Kilo is 2.4%

The difference for Mega is 4.8%

The difference for Giga is 7.3%

Be careful when you buy a hard disk

Binary is practical but hard to write

First, we separate in groups of four

Then we replace every group of four by a number or letter

Sometimes Web address use HEX symbols
