Johannes Kepler (December 27, 1571 – November 15, 1630), A Key Figure In The 17th Century Scientific

Johannes Kepler (December 27, 1571 – November 15, 1630), a key figure in the 17th century scientific revolution was born 444 years ago today. 

The three laws of planetary motion are Kepler’s most well-known but far from his only contributions to astronomy. His 1604 Astronomiae Pars Optica is credited with founding modern optics, describing the process of refraction inside the human eye and the means by which two eyes gives us depth perception. His book Stereometrica Doliorum (1615) was the basis of integral calculus. Kepler was also the first to suggest that the Sun orbits around its own axis, and he invented an improved version of the refracting telescope and a bunch of other things.

Now, his name lives on with Kepler space telescope launched in 2009 to discover Earth-like planets orbiting other stars.

Just Before Leaving The University After A Long Day. 

Just before leaving the university after a long day. 

Chemists usually work 24/7/365 and always have deadlines. Always. Now for a paper, now for a grant. So after the experiments and a really long day, I’ll go home and write something.

Today is the day I've discovered about NFT's.

Today Is The Day I've Discovered About NFT's.

First it was physical currency that was digitized, now even physical objects have joined the the digital boy band. I have come to know how NFT's they work, how to create them and eventually sell them, now that's my ultimate goal.

Today Is The Day I've Discovered About NFT's.

It's still a process, but I've gained so much interest that I decided to be all hands on deck. One thing. I'm aware of is that you have to be original in all aspects, otherwise your creative work, qualifies as a fake.

Today Is The Day I've Discovered About NFT's.

Photos or image you produce must be your own work, not copycatting. When it comes to people's photographs especially, you most probably must get a consent from the said individual before using their photos as your creative work, for publishing purposes.

Hello Friends, It's Your Friendly On Duty. Thought I Have A Word With You, You See, I Love ❤ What I

Hello friends, it's your friendly on duty. Thought I have a word with you, you see, I love ❤ what I do not be because it's a job or a means to earn a living, but because it's a #CAUSE, a service I provide to society to keep my neighbourhood safe and give peace of mind. It's not about what you have that matters, but what you do with it that matters the most, you see, people have lost sight of what it's all about, yes you do need to fill your tummy in order to energize your bodily systems to function, but let that not be the focal point 👉 as to why do whatever it is that you do for a living. You see I have come to realize that, there's no big or small job, more important or less important, because everything is interconnected and that's how it need to be for all to work, live and exist in harmony otherwise there's chaos, which is what's currently taking place because it's like nothing I have aforementioned. Some people see themselves as superior than others, some think what they do is what keeps the ball ⚽ rolling, you see, we must always look at the bigger picture 📷 of things, and find their significance in the world, for instance...without the kind of service I provide to society, what then?, "Your ass is fried"! So look at it this way...no matter what society may have led you into thinking 😔, we are actually all equal beneath our skins in aspects of our existence, no matter how you try to excuse yourself from it. The only thing that will make it bearable for all of us, is for us to accept the inevitable, and use love ❤ as our ultimate weapon to get through this thick mud of self inflicted confusion. #LetLoveWin! Peace ✌ out.
