Sorry To Be Out

Out Of The Office

I am sorry, I have a family.  I will begin posts again after a family issue is resolved.  Many of you have kids and know what happens when we have issues with kids.  We get distracted.  For days, weeks, months.  I am beginning to come back to the blog to take care of the insatiable appetite of my buddies on this topic of sonography.  The topics are many.  I have much work to do.  I will not make posts at work because it is not allowed. Employers frown upon blogs.  So Be It.

I have a few topics to post, as a Sonographer.

The lion is a funny, but a real thing that a taxidermy person made poorly.  I l love it!

I cannot find the link to credit the person who took this picture. 



Bats.

They send out ultrasonic pulses where prey is in space. This is basically what bats do.  They use echolocation for the food with sound.  The pulses are ultrasound.  They tend to find a meal with ultrasonic waves of energy. Sound waves. Like we use our car horns to tell another person to move at a stop sign.  They have misshapen ears, and crazy noses, and they are for echo locations.  The noses and ears are for the radar of the prey they feed on.  Insects are primary, though many feed on fruit, and some on cows for blood.

” That’s how the science podcast Invisibility recently described Daniel Kish, a blind man who taught himself how to navigate by echolocation. But their description slightly misses the mark. While both humans and bats can paint visual landscapes from echoes, the pointy-eared flyers possess a stark advantage: ultrasonic sound."  

Interesting:    Many humans who are blind use clicking noise they generate with the tongue to find a way around.  Bats do it.  Humans should be able to adapt.  And they have.  This is interesting article.
