PY 131 Chapter 1 Conceptual Academy

**Equations in Conceptual Physics are used mainly as**

Guides to thinking.

**A theory in science is**

a synthesis of well-tested ideas.

**A fact in science is**

an agreement between trained investigators.

**A scientific hypothesis deemed valid must have a test for proving it**

wrong.

**The scientific method of Galileo and Bacon is**

one of many ways of making discoveries.

**Science is concerned mainly with the**

natural world.

**Technology is a tool for**

applying scientific discoveries to social problems.

**Which of these is the most basic science?**

Physics.

**The Greek mathematician Eratosthenes made measurements to show the size of**

Earth

**The distance between Earth and the Sun is about**

110 Sun diameters.

Eratosthenes found the Sun’s position on June 22 by

consulting library information.

A well-balanced education requires an understanding of

science, the arts, and religion.

To measure how far between the Moon and Earth you can

hold up a coin.

Intelligence, passion, and talent help one do well in

art, literature, and the sciences.

Without a special filter, the Sun can be safely viewed by looking

at pinhole images.

What is the nature of science?

Science describes order in nature, science is an ongoing activity of humans, and science condenses knowledge into testable laws

Art, science, and religion

help us make sense of the world, complement each other, and work in different domains.

The most basic science is

physics.

**According to this video, any observation must be measureable as well as**

reproducible

**According to this video, science has a focus on**

reasoning.

**Any scientific claim must be supported by**

experimental results.

**[Dry wood burns] is an example of a scientific**

fact.

**[Mass is conserved in a chemical reaction] is an example of a scientific**

law

\[Local temperatures are a bit warmer this year because of the El Nino conditions occurring the Eastern Pacific Ocean\] is an example of a scientific

hypothesis

In the year 0 AD, the world population of humans was about

200 million

The world population of humans is now about

7000 million

For a scientist with a Ph.D. , the letters Ph.D. stand for

doctor of philosophy.

Technology is the practical application of

science

Which is the best statement:

Science and technology arise from each other.

As per this video, physics is the study of

the rules of nature.

The most complex science is

biology

According to this video, the scientist is a natural

skeptic

According to this video, all evidence is subject to

interpretation

According to this video, substantiated claims are more willing accepted by

the skeptic
