Wisdom from Kenneth Miller Summarizing The Point of

TodayThe point is to UNDERSTAND the scientific theories and the evidence for them

Good luck deciding what to believe in

This is not “Religion vs. Science”

I believe I believe in a in a

creator, creator, not in the not in the big bangbig bang

I believe I believe in the big in the big bang, not bang, not a creatora creator

Wrong words! These people don’t understand the difference between religion

and science!

Religion ScienceSomething you may choose to believe in

Not falsifiable / not testable

Something to understand, not believe in

Must be falsifiable / testable & repeatable

This is not “Religion vs. Science”

I believe I believe in a in a

creator, creator, not in the not in the big bangbig bang

I believe I believe in the big in the big bang, not bang, not a creatora creator

These people imply that science is something to either believe or not believe

There’s Lots of Possible Perspectives

Have a cultural belief and understand science

Not have a cultural belief and understand science

Have a cultural belief and not understand science

Not have a cultural belief and not understand science

Others...?

Well informed

Not Well Informed

Why we teach, not preach

Separation of church and state...

We teach you to understand science

We teach you that there are cultural beliefs

We don’t preach to you which one to believe, if any.

Creation MythsDifferent cultures all over the world have different stories describing how the world began

These stories are called “creation myths”, but the word “myth” simply refers to story, it is not meant to imply false.

We’re going to share a few here. Be respectful. You might think one story sounds silly, but it may be the cultural underpinnings of the person sitting next to you.... maybe they’re thinking this about your family’s beliefs. Mockery is strickly forbidden.

Tlingit:Raven and the Sun

Judeo-Christian: 7 Days

Hopi- The infinite creates the finite, created a God to create the universes

Aztec: One God looked over the

darkness--> birthed 4 other gods--> created Earth

Iroquois: Island floating in sky, where sky people lived, hole in the island, creatures

below...

ZuluThe Ancient One, known as Unkulunkulu, is the Zulu creator. He came from the reeds and from them he brought forth the people and the cattle. He created everything that is: mountains, streams, snakes, etc. He taught the Zulu how to hunt, how to make fire, and how to grow food.

Greek: Titan goddess,

bride of Zeus

Others?....

What Similarities and Differences Do You

See?Creation ex nihilo in which the creation is through the thought, word, dream or bodily secretions of a divine being

•Earth diver creation in which a diver, usually a bird or amphibian sent by a creator, plunges to the seabed through a primordial ocean to bring up sand or mud which develops into a terrestrial world

•Emergence myths in which progenitors pass through a series of worlds and metamorphoses until reaching the present world

•Creation by the dismemberment of a primordial being

•Creation by the splitting or ordering of a primordial unity such as the cracking of a cosmic egg or a bringing into form from chaos

Religious/Cultural Beliefs & Science Are Very Different

ThingsScience must be falsifiable, testable, repeatable

Faith based beliefs are not, hence the faith

THIS DOES NOT MEAN ONE IS BETTER THAN THE OTHER, they are simply totally different ways of trying to understand our world

Scientists Are Skeptics, (but this does not mean atheists)...

Kepler (Protestant): had vision of God as the designer of a rational cosmos

◦Platonist: the divine order could be expressed in mathematical terms (Bowler & Morus, p. 351)

•Newton: Cosmos as a divine construct (Bowler & Morus, p. 350)

•Jesuits: active in many areas of science, including astronomy (though they favored the old cosmology)

•Buffon: days of creation correspond to geological epochs

•Robert Boyle: “conceded that it was in the study of living things that we see the clearest evidence of the creator’s handiwork” (Bowler & Morus, p. 353)

•Jocelyn Bell (Quaker): Discovered pulsars while working at radio astronomy observatory

What Does the Word “Theory” Really Mean?

LOTS of words have very different meanings in everyday life than they do in the context of science (theory, law, fact...)

As such, they are often misused and misunderstood

-Mock Congress Example-

TheoryCurrent explanation, subject to peer review, based on overwhelming amounts of evidence, which may still change someday as evidence changes

So There’s Lots of Theories, Right? One at the end of every

science experiment???

No! This has been misused

and misunderstood

.

What Theories Exist in Modern Science?

Theory of Gravity

Theory of Evolution

Big Bang Theory

Heliocentric Theory

...a few more, but that’s it!

The Big Bang Theory

28.3 The expanding universe

Edwin Hubble discovered that the farther away a galaxy was, the faster it was moving away from Earth.

This concept came to be known as the expanding universe.

28.3 The Big Bang theory

The theory that the universe was expanding implies the universe must have been smaller in the past than it is today.

It implies that the universe must have had a beginning.

Astronomers today believe the universe exploded outward from a single point.

This idea is known as the Big Bang theory.

28.3 The Big Bang theory

The Big Bang theory says the universe began as a huge explosion between 10 billion and 20 billion years ago.

According to this theory, all matter and energy started in a space smaller than the nucleus of an atom.

28.3 Evidence for the Big Bang theory In the 1960s, Arno

Penzias and Robert Wilson were trying to measure electromagnetic waves given off by the Milky Way.

The “noise” these scientists found was the cosmic microwave background radiation predicted by the Big Bang theory.

28.3 Evidence for the Big Bang theory

The proportion of hydrogen to helium is consistent with the physics of the Big Bang.

If the universe were significantly older, there would be more heavy elements present compared with hydrogen and helium.

A large part of this book is about why creationism isn’t

science. Don’t misunderstand this and think it’s anti religion, it’s not. It’s simply about the difference between science and religion. Miller is both a famous biologist AND a very

religious person.

Let’s Try Some Spectroscopy

diffraction grating

=plastic with thousands of lines in it, functions like a ton of prisms!

(look at some spectral outputs, after Helium, play remaining slides,

then look at some more)

Helium

How would it look if it was moving fast away from

you?

exit slideshow and move the bar!

infrared

Stationary Helium Light

Source

Helium moving away super fast

showing red shift

So: we can see the light fingerprint of elements like this on Earth, and when we look into space, we can

recognize the same light fingerprint patterns, but the farther & faster

away the star or galaxy is, the greater the red shift!
