Fun Friday – August 10, 2018

Today is for all science geeks. In 1591 it is said that Galileo (at the time, a mathematician at the University of Pisa – the location of the leaning tower…) proposed that a feather and a cannon ball would fall at the same rate of speed if there was no air resistance. In other words, gravity is an equal force no matter the size or weight of the object. Nearly 100 years later Isaac Newton mathematically proved the theory of gravity building on the earlier idea of Galileo.

Brian Cox and the BBC put this to a test. In rather dramatic fashion. Make sure to watch through to the end and hear what Einstein thought of it all.

All I can do is sit in wonder at God’s creation. An endless expression of creativity and design.

    Very cool! It’s wonderful how God has blessed us with so many things to marvel at. Thanks for sharing.

    So cool! (I guess that makes me a science geek.)

    That was so beautiful! I love how enthusiastic the narrator is about this aspect of science. One cannot wipe the smile off that guy’s face.

    God is truly amazing!

    WOW, our God is Amazing!!! And, yet again, we see His perfection through science as it points to HIM!

    What beauty and grace! This reminds me of the verse “Be still and know that I am God,” for then we walk in beauty and grace indeed. (Science is not at all my field, but if the feather and ball are not moving, perhaps the movement of the earth itself (rotation/revolution) causes the impact.) Thank you for this fun and intriguing post!

      Oh my—it was way too early in the morning for me to hypothesize! I did take that class and indeed knew it was gravity! One can only imagine the chaos of the world I “created” (lol).

    That is so neat! Crazy to see them falling at the same rate!

    One of my brothers is an electrical engineer, so this kind of stuff has always been interesting. Einstein’s comment cracked me up, though; it would seem he always had something to say about anyone’s inventions or theories . . . I tried to picture a blank background as the feather and bowling ball were falling, and I imagine you wouldn’t see them falling but rather standing in place. Wow. Gravity is one of the neatest elements God created.

    Your statement is incorrect: “In other words, gravity is an equal force no matter the size or weight of the object.”

    The force on objects is larger for heavy objects than light objects. That’s what we mean when we say something is heavy or light.

    What is equal for all objects (in the absence of air resistance) is the acceleration due to gravity, which is the force divided by the mass.

      I must have slept through that detail in science class over 40 years ago.

    Thanks Steve, for posting something on science, which is both my profession and my subject. And I join the chorus of those who proclaim the glory of God’s creation as manifested by human scientific discoveries. (which is my theme).

    The Einstein quote at the end refers to his pioneering extension of Newton’s law, the general theory of relativity, which probes deeply into the inner mechanism of gravity, beyond the Newtonian description of how it works.

    Mind blown to think that someone could even imagine the truth in such science!

    I was taught this in my college science courses but I’ve not seen such a dramatic demonstration. Fascinating! As a true geek, I have to agree with Randy’s statement but, regardless, it shows God’s glory as Creator. He designed His creation with absolute precision.

    I remember learning this way back when. But being geek-less, it is amazing to see Newton’s revelation within mathematics (only God-given) in action.

    I think of Colossians 1: 15-20.

    My husband and I watched the history of Voyager 1 and 2 today. The scientists search and search and find emptiness, they wonder why we are alone. Then they decided we are to save ourselves.

    How’s that working out of ya, guys?

    It’s wonderful to contemplate how science has moved closer to God’s truth through the ages. Reminds me of Proverbs 25:2

    “It is the glory of God to conceal things,
    but the glory of kings is to search things out.”

    I suspect God must smile when He sees His children solving a piece of the puzzle.

    Great video!

      Kay, indeed. It was my growing understanding and appreciation of science that turned from atheism to Christ. And I agree with you and all of the Christian scientists of the past (Newton, Galileo etc) that science is the way to read God’s “book of Works” – His creation of the natural world.
