From biology to the cosmos, this is all things science.

Wow, you should see all of the topics they have to choose from. I now know what I can do with any “extra” time that I have. haha, extra time….funny.
In a previous post, I shared with you that friends of mine performed a “wives tale” gender test on me. This is the test that includes a needle on a string, and if the needle moves in a circle, it’s a girl. If the needle moves back and forth, it’s a boy. Their test predicted I was having a girl, while a former Army Ranger instinctively predicted a boy (and had not been wrong in at least 6 years).
Well, I went this past Friday for what is call the “Anatomy Sonogram.” This is when the ultrasound tech will identify all the body parts and check blood flow, count fingers and toes, etc. Our child wasn’t being shy at all apparently because as soon as she received the first image, she shared that we were having a boy. I was glad there was no hiding or guessing. It was obvious and clear according to her trained eye (as mine had NO idea what she was looking at without the little arrow. Hopefully, he’ll outgrow the need for that arrow.)
Also, as a follow up to the Googling post about Hertz (more specifically Carl Hertz), I thought I would update the sonogram photos to show the progression in growth since the last photo which was at 13 weeks gestation. The top left photo shows the profile of our son. It’s clear to see the eyes, nose and mouth. I am so proud! 🙂
Next to the right, we have a 3D image of our child with his right hand up by his face, his legs are pulled up in front of him and his left hand on the far side. In one version of this photo, it appears he may have been sucking his thumb, while this photo doesn’t show that as clearly. This is more than a mother merely showing excitement about an expectant child. The excitement that I feel is also about the advancement of science and technology that permits us to even see these images. How wonderful is that?! As a country, we do need to continue to focus on the areas of math, science and technology. Who knows what future images could produce.

I don’t know about you, but when I log into my computer each morning, my browser loads to Google. Google is my preferred search engine, and maybe in part because of their humor.
This morning, I couldn’t help but smile when I noticed the image here (of course it’s animated on Google’s page, so check it out) because you really never know what those characters are going to do with their logo. Of course as usual, when I see an altered Google image, I click the image to read who they are paying a tribute to for that day.
Today’s tribute goes to Heinrich Hertz who is responsible for proving the existence of electromagnetic waves. Of course this information has gone on to contribute to all sorts of electronic devices. Hertz died at the very young age of 36 from Wegener’s Granulomatosis.
What I found very interesting was the fact that his nephew and great nephew also made huge contributions to the field of science. The contribution that caught my eye (and heart) was that of his great nephew Carl Hellmuth Hertz who invented medical ultrasonography. The reason this is so special to me is because I am expecting my first child, after years and years of believing I could not conceive.
For a family who has accepted that they would never have a child, this image was completely breathtaking, hugely emotional, and life changing.
I am very thankful to the work of the Hertz family and join with Google in making my blog a tribute to his work and the work of those he influenced along the way.
