The video is a lecture on farming and fishing, with a focus on increasing the efficiency of food production. The video discusses various techniques and methods to increase the transfer of energy between levels in a food chain, including...

The video focuses on the concept of energy dissipation and how it occurs in various systems. It begins by explaining the principle of conservation of energy and then goes on to provide examples of closed and open systems. The video then...

During the day, Luna loves playing outside in the warm sun. Why can’t it always be daytime and playtime? Why does it become dark and cold when the sun sets? One night, Luna makes a new friend, Mr. Bat. Join Luna as she learns about the...

In this week’s episode, we test a new breed of drones that can navigate without GPS; we explore changing terrain with shapeshifting autonomous robots, and finally, we examine a new 3D bioprinting technique that could someday create...

The video is a tutorial on how to investigate temperature changes in chemical reactions, specifically focusing on the concepts of exothermic and endothermic reactions. The video explains the definition of the two terms and provides...

On this episode of Breaking Trail, the Brave Crew is on location in Costa Rica, and they FINALLY find a very special frog... the Splendid Leaf Frog! This is one RARE frog and it is sure to surprise you!

How do we define the system? The surroundings? In this video, we explore this along with energy transfer between system and surroundings in the forms of heat and work. We also do a sample calculation of total energy (E = q + w).

Scientists have observed some copepods eating over 300,000 diatoms in a single day!

The video discusses the concept of unwanted energy transfers and ways to reduce them. The video highlights two examples of how energy is lost through friction and conduction, and presents solutions for each case. For friction,...

What’s your favourite season – summer, autumn, winter or spring? Meet new friends like Misty the cat, Moonshine the possum and Wendy the whale. Discover how our environment changes with each season.

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

This video explores the concept of snow camouflage in animals, focusing on how different species adapt to changing seasons and the role of photoperiodism in color changes. The video also explains the molting process that warm-blooded...

James, our master of microscopes, gets samples of sand from beaches all over the world to help in his quest to learn more about interstitial ciliates—the single-celled organisms that live in the watery pockets that exist between grains...

This video talks about the environment.<br<br/>/>

This clip is from the chapter "Terminologies of RL" of the series "Reinforcement Learning and Deep RL Python (Theory and Projects)".This section focuses on the terminologies of RL.

Everyone says that the ‘optimum’ body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit). But if the temperature of your surroundings is 37 degrees Celsius, most people will start to feel warm or even hot. Why does that...

This video is a lecture about energy dissipation and efficiency. It begins by defining what efficiency means in energy transfer processes and how it is calculated. The video provides examples of calculating efficiencies in different...

The video discusses the factors affecting dynamic equilibrium by explaining the difference between exothermic and endothermic reactions, and how they relate to reversible reactions. The concept of dynamic equilibrium is explained using...

Explore the fascinating function of whiskers in animals. We will learn how whiskers aid vision, serving as touch receptors, and providing a heightened sense of feeling. The whiskers play a crucial role in helping animals navigate their...

We also don't really know what rotifers are... but we'll try to tell you as much as we know!

What the heck is entropy?! You've heard a dozen different explanations. Disorder, microstates, Carnot engines... so many different wordings and interpretations! Really, they are all related, so let's go through a few different...

It explains the different types of materials around us and their sources.

It describes the characteristics of living things and differentiates between living and non-living things.

The video discusses how diagrams of reaction profiles can be used to show the energy changes that occur during chemical reactions. It explains the concept of energy conservation in chemical reactions and how the transfer of energy to or...

Did you know that everything is moving? Even you, as you're sitting perfectly still, because the earth is moving, and the sun, and the galaxy, and so forth. For this reason, it only makes sense to talk about the motion of some object...
