Title: SCIENCE
1SCIENCE
"The most beautiful thing we can experience is
the mysterious. It is the source of all true art
and science. Albert Einstein Nothing in life is
to be feared. It is only to be understood. Marie
Curie A scientist in his laboratory is not a mere
technician he is also a child confronting
natural phenomena that impress him as though they
were fairy tales.
Marie Curie was the first woman to win a Nobel
prize and the first person to win two Nobel
prizes.
"Science contributes to our culture in many ways,
as a creative intellectual activity in its own
right, as the light which has served to
illuminate man's place in the universe, and as
the source of understanding of man's own
nature. John F. Kennedy
2In the field of observation, chance favors only
the mind that is prepared. Louis Pasteur
SCIENCE OBSERVATION
God hides things by putting them near us. Ralph
Waldo Emerson
To acquire knowledge, one must studybut to
acquire wisdom, one must observe. Marilyn Vos
Savant
You are one of the rare people who can separate
your observation from your perception...you see
what is, where most people see what they expect.
Tsitsi Dangarembga
The ability to make careful, complete
and unbiased observations is one of
the attributes of a great scientist. What do you
observe in the following slides?
3Can you find the perfect 5 pointed star in the
figure below?
It is relatively small and in the bottom half.
4Report your observations about this figure.
Young woman?
Old woman?
Perhaps one or the other or neither or
both. Recorded observations should describe the
figure and not come to definitive conclusions
about its content.
5Report your observations about this figure.
A rabbit, looking right?Or a duck, looking
left?
Or just an artists drawing designed to
create disagreement depending on perspective.
6birds, tree?
flowers, butterfly?
branches?
or beautiful women?
7Is this a person?
Uh, Oh! Not everything is as it appears.
Sometimes the brain does not interpret
information correctly. In this case and in many
other cases, interpretation depends on
perspective.

9Good doormat?
Sure!!!!
10Frog?
Or Horse?
11 Color Blindness Tests The following are common
tests used to detect color blindness.Can you
read the numbers or letters hidden in each
square?
You should see 58 (upper left), 18 (upper
right), E (lower left) and 17 (lower right). If
you cannot see any of the above numbers/letters,
you may suffer from color blindness.
12Can you read the words?
13What is above the womans head?
Is it a window, a picture or a container on her
head? The description of your observation should
not depend on your cultural background and should
describe the object without concluding what it
is.
14What is the symbol in the middle?
Perception depends on the environment. If you
block out the 12 and 14, your answer is probably
a B but if you block out the A and C, your answer
is probably the number 13.
15Who are the people in these pictures?
Both are Bill Clinton. Clinton and Gore (look at
the faces)
16 Can you count the black dots?
17Parallel
Are the horizontal lines parallel, or do they
slope?
18Is the figure a perfect square or is it
a trapezoid?
perfect
square!
19Is the vertical line on the right longer or the
same length as the one on the left?
same length!
20SPIRAL OR CIRCLES?
21Is the SUV in the back larger than the one in
front?
No!!!!!
22Is there movement?
23Do you believe that A and B are the same color
and intensity? If not, watch when
the surrounding squares are blacked out!
What is the color and intensity
relationship between A and B?
24Working in a glove box good science! Or is this
bad science?
25From Parade Magazine, 12/05/2010 Jack Black is
cooking up a reimagined Gullivers
Travels. What is Jack doing that Is against all
chemistry safety guidelines?
26This is called an "impossible object", which
means that it's impossible to build. But drawing
it is not impossible, as you see in the image.
27Now what do you see?
You may not see it at first, but the white
spaces create the word OPTICAL, while the blue
landscape spells out ILLUSION.
28This one is quite interesting! The word TEACH
reflects as LEARN.

30Pick a number between 2 and 10.Multiply the
number by 9. Add the two numbers together (e.g.,
for 18, 18 9). Now subtract 5.Right, now map
the result to a letter of the alphabet, where
A1, B2 and so on.Think of a country which
begins with that letter.Take the second letter
of the country and think of an animal which
begins with that letter.Think of the color of
that animal...
31You're thinking of a grey elephant from Denmark,
right?
32Chemists use the mole as a basic unit. One mole
is the number of atoms of carbon in 12 g (0.42
oz) of carbon or 602,000,000,000,000,000,000,000
atoms (6.02x1023 atoms) Would a mole of
marshmallows cover the 48 contiguous states of
the U.S. ?
diamond graphite buckyballs
The three forms of carbon.
33Your first response should be what size
marshmallows? Assuming regular size
marshmallows, a mole of marshmallows would cover
the United States to a depth of about 600 miles.
When you drink a glass of water, you
swallow about 10 moles of water or 6 septillion
(6x1024) 6,000,000,000,000,000,000,000,000 molecul
es of water. Recently it was reported that the
Universe has 1/2 of a mole of stars.
9.6x10-11 m 3.8x10-9 inches teeny, tiny!!
Notice that water is not linear but bent. As
a result, water is polar and has unusual
properties.
34Each of the two beakers below contains only one
substance. Which substance exhibits abnormal
behavior?
acetophenone water acetic acid
dioxane p-xylene
oleic acid
Acetophenone Water
Because water is probably the only substance for
which you ever see both the liquid and solid
phases in the same system, you have probably
accepted the observation of its behavior (solid
floats in the liquid) as normal. However, if you
think about it, the solid should be more dense
than the liquid and sink. Almost all substances
other than water behave like acetophenone so
water (fortunately for us why?) behaves
abnormally.
35The best way to have a good idea is to have a
lot of ideas.
Linus Pauling (1901 1994), the only person to
have ever won two unshared Nobel Prizes
(Chemistry 1954, Peace 1962) He attended
Washington High School in Portland but because of
a technicality did not receive his diploma until
1962, long after he had received his bachelor's
degree from Oregon State College in 1922 and his
doctorate from the California Institute of
Technology in 1925.

38Rachel Carson, author of Silent Spring,
deserves significant credit for initiating the
environmental movement.
Only within the moment of time represented by the
present century has one species -- man --
acquired significant power to alter the nature of
his world.
One way to open your eyes is to ask yourself
What if I had never seen this before? What if I
knew I would never see it again?
Those who dwell, as scientists or laymen, among
the beauties and mysteries of the earth, are
never alone or weary of life.
