iBilib: Submarines vs. Ultrasound Machines

GMA Network

Aired (June 2, 2024): What do submarines and ultrasound machines have in common? Join us as we unravel the connections and unveil the secrets behind these seemingly disparate innovations.

00:00Dolphins use different senses to eat, move, and talk, and they are one of the inspirations for the high-tech vehicle I'm talking about.

00:15If animals can navigate with the help of echolocation, we have invented sonar used in submarines.

00:23Sonar or sound navigation and ranging is the same echolocation used by animals.

00:29It produces sound in sequence to detect things, track movements, and communicate with other submarines.

00:37Dolphins and whales inspired the sonar of submarines.

00:41Because of these sea creatures, humans invented something.

00:45That's why when you see a submarine going up to the sea, they probably saw the land you are building before you see them.

00:55Let's look at another invention that came from the use of sound.

00:59Sound is its name.

01:02Dolphins use ultrasonic sound waves to create images.

01:07That's also what an ultrasound machine does.

01:10If you have seen an ultrasound of a baby before it was born,

01:15that image was made by a computer with the help of technology that can pick up bouncing sound waves at a high frequency that we can't hear.

01:25The image of the baby is formed.

01:27Because of this, the doctor can be sure that the baby is healthy in mommy's womb.

01:33The sound waves are amazing, Chris! I'm mind-blown!

01:37Mind-blown?

01:40You'll probably be more impressed with my brain-bender question about our brain.

01:46We already have a lot of mind-blowing discoveries about sound waves.

01:49Next, we'll talk about and think about brain waves.

01:54But before that, here's my brain-bender question.

01:57True or false, there are approximately 170 billion cells in the average human brain.

02:05Wow, Chris! That means there are 170 billion cells in my brain?

02:10To visualize how many 170 billion cells there are,

02:15imagine that one of our hands can hold 2 million grains of sand.

02:21If each brain cell is a grain of sand,

02:26you need about 85,000 hands to hold 170 billion grains of sand.

02:34Wow, that's a lot!

02:36If that's the case, my answer to your question is false.

02:41What do you think, iBelievers? Is it false?
