Radiation Health Effects

Today's videos for radiation dose rates.

Part II includes the exciting conclusion.....

Nuclear Fusion

A few videos to transition you to the ideas of the Thermonuclear era.  First up, let's settle a general misconception about the 'power' of nuclear bombs.

A refresher of the basics of Fission and Fusion.

Duck and Cover

Nuclear Effects Simulator from today



Ivy Mike, where we learned that H-Bombs would change our concept of living in a a nuclear world.

Castle Bravo, the biggest (by accident, rather than design) weapon detonated by the United States.

Tsar Bomba, the biggest weapon ever detonated.

The result of the advent of Thermonuclear weapons would be the transition from the idea of waging atomic war to one of "Mutually Assured Destruction"  The US and USSR would end up constructing massive nuclear arsenals with the intent of using deterrence as the primary means of preventing a nuclear war.

Next time we will deal with the idea of Nuclear Fusion as a means to provide vast amounts of useful energy rather than the threat of destruction.


If you want to see some cold war memorabilia check out atomic annihilation. 

Radiation Units

If you are still feeling some confusion on Radiation Units, here is another source to explain what dose and equivalent dose means.

Another attempt

How old is the earth?

What is the currently accepted scientific age for the Earth? What was the evidence presented in the videos to support that number?

What are the challenges to determining the age of the Earth?

Why do we need to use moon rocks and meteors to help us determine the age of the earth?

Radiation Videos

Some videos to help you on your way to greater understanding in nuclear radiation

First up Nuclear Radiation vs. "Radiation"

A series from Veritasium giving us an Auzzie twist.

More Hank Green, this time the basics of Nuclear transmutation.

Nuclear Nostalgia

Questions:

What has changed in our understanding of Nuclear Energy since this film was created?
What predictions from the video came true?
Which predictions did not happen?  Why?

Video for Today (9/10/21)

For those that missed class today here is a video to watch:

• Some simple questions from the video:
• What is a force?
• Define the four fundamental forces.
• Identify two things you learned from the video
• What are two questions that you have following this video

Fundamental Forces

Here are some videos to support the ideas of fundamental forces

Maybe you are tired of Hank, so try this

Some questions to consider

• Identify, and briefly explain each of the four areas of Modern Physics introduced in this class.
• What is/are the relationship(s) between the fundamental forces?
• How does modern physics differ from "classical" physics?
• Why is modern physics so interested in the origin of the universe? (Cosmology)
• What is the significance of the following principles/laws:

• Cosmological Principle
• Pauli Exclusion Principle
• Heisenberg Uncertainty Principle
• Plank Length

Structure of the Universe

This video provides some good visualizations for the organization and structure of the universe

Welcome to PHS Physics

Welcome to PHS Physics.  If you aren't taking Physics at Pullman High School, this is probably not the place for you.  This is simply intended to be a quick update site for posting assignments and announcements for the class.  I will try to post useful stuff as pages with assignments as updates.

If you miss class, I will often have alternate assignments or supplemental information you may find useful. 

Here is a Quick Guide to the site:

• Top Bar:  Your Syllabus and anything else useful I throw up there for long term consumption.
• Upcoming Schedule:  This is a living document.  I will let you know if I make significant changes.   I try to keep it about three weeks out, but things change as the class evolves. 
• Text Book Assignments:  If this needs explanation, you are in the wrong class.
• Upcoming assignments and major emotional events:  Look here for items that specifically affect your grade.
• Useful Links:  I am always open to suggestions if you find something more up to date and/or useful
