Season 1: Loops – Is Time a Flat Circle? Part 2

How many times has the universe exploded in a great Big Bang? And if the answer is ‘more than once’ then that poses an even more important question: does Time stop and start over with every Bang?

To answer this, we have to go back to the very  beginning of the universe (if indeed there was a beginning…) to a “time” before mass, matter, and possibly Time even existed at all.

Season 1: Loops – Is Time a Flat Circle? Part I

What is time? A line? A loop? A figment of our imaginations? Spoiler alert… no one knows. But we can use what we know about physics, biology, and Einstein’s ideas about Relativity to take our best guess. Join K+K on this 2-part journey into the center (if there is such a place) of time (if there is such a thing)!  In this show:

  • How does the human brain keep track of time?
  • Why is syncing up our biological rhythms with the sun’s cycles so important?
  • If someone kidnapped you and you woke up in a sensory deprivation tank, would you ever know what time it was again?
Are you the glucose monster or the melatonin fairy? Be honest.

Re-Release: 6th Grader Questions, Part II (edited & updated)

The kids from Mrs. Pace’s 6th grade class at Pleasant Valley Middle school in Vancouver, Washington sent us so many excellent science questions, we had to take 2 whole episodes to answer them all! This week K+K tackle:

-How the Earth was formed
-Why the Earth’s axis is tilted
-Where Earth’s first water came from
-What the Earth’s first plant was
and weirdly,
-The temperature on the moons of Neptune

Re-Release: 6th Grader Questions, Part I (edited & updated)

In a special “Listener Question” episode of Everything is Interesting, K+K answer some excellent inquisitions, sent in by the kids from Mrs. Pace’s 6th grade class at Pleasant Valley Middle school in Vancouver, Washington. The science ladies tackle:

-The physics of flying in a V-formation
-Why there’s droughts when the world is covered in water
-The magic behind Magnetic Levitation
-The strange & wondrous ways mosses reproduces

Season 1: Loops – Thought Loops & Habits

Its a new year! That means its time to make some resolutions about picking up new, healthy, shiny habits! Habits that will definitely become part of your routine right away and you’ll do them every day and you’ll never break them even when you get super stressed out at work because of that one lady that always comes in and gets on your last nerve and the next thing you know you’re eating chocolate chip cookies… right?

Why are bad habits so hard to break, even when we rationally know better? Why do we replay the same thoughts over and over again in our minds, even when we don’t want to? Is it possible to rewire our neural pathways in order to break the old, bad habits in favor of some healthier, more conscious decisions? (Spoiler: yes, yes it is.) Join K+K and guest David Zimelis to find out!

Season 1: Loops – Life-cycle Loops (Part I)

All living creatures on earth reproduce themselves in some way or another. But there are so many different ways to make a baby,  virtually the only commonality is that DNA inside one organism is copied and then passed on to an offspring organism. And usually, the offspring will grow, reproduce, and die in the same way, completing the same loop, as their parent. 

Today K+K, and guest co-host Paul Francis, explore some of the world’s weirdest life-cycles, and the lengths some creatures will go to in order to keep the life-cycle chain unbroken.

He can’t WAIT to tell you about eating his own bones!

Season 1: Loops – Wild Wolves & Feedback Loops

Kira and Keera are trying something new: seasons! With themes! In Season 1, they’re exploring the idea that in nature, many processes happen in reoccurring patterns, or more specifically, loops.

In today’s episode, K+K dive into how important, and also difficult, it is to keep ecosystems in balance. They talk to Alma Frankenstein, Project Manager for the Cascadia Systems Institute, about how the natural world keeps itself from completely falling part, through the use of positive and negative feedback loops.

Then they use this knowledge to tackle a debate that has been waging in the U.S. for nearly 100 years: is the big, bad Grey Wolf really bad? Should we continue to guard its population under the Endangered Species Act, or is this dangerous predator a threat that needs to be eradicated?

Come along and ride on a fantastic Science Voyage, and find out!

Re-Release: The Science of Love (Edited & Updated)

Love. Some would say its the reason for being alive. So why does it make you feel sweaty, shaky and nauseous, like someone’s forcing you to jump off a bridge at gunpoint?

Join K+K to discover what’s happening inside your body when you fall in love, why we give out little candy hearts on Valentine’s Day instead of candy brains, and whether or not the characters from Wayne’s World will ever find their true soulmates.

  • LAVA!
  • The discovery of plate tectonic theory
  • The Cascadia Subduction Zone
  • Crater Lake
  • Yellowstone geysers and the ocean of magma beneath them
