<p>Today I am going to teach you a bit more about telescopes and &nbsp;binoculars. &nbsp;&nbsp;</p>
<blockquote><a href="https://www.thoughtco.com/carthage-116970">Phoenicians</a> &nbsp;cooking on sand first discovered glass around 3500 BCE, but it took &nbsp;another 5,000 years or so before glass was shaped into a lens to create &nbsp;the first telescope.</blockquote>

<blockquote><a href="https://www.thoughtco.com/hans-lippershey-3072382">Hans Lippershey</a> &nbsp;of Holland is often credited with the invention sometime in the 16th &nbsp;century. He almost certainly wasn’t the first to make one, but he was &nbsp;the first to make the new device widely known. Did you know that glass &nbsp;is made from sand?&nbsp;</blockquote>
<p>It was discover from melting lava onto sand and they used this to &nbsp;make tips for their spears. It was hard enough to form tips and was well &nbsp;used to kill as it could be made very sharp.</p>

<p><a href="https://imgoat.com/uploads/7d1e990583/147606.jpg">image source&nbsp;</a></p>
<p>It was only later that the Romans who knew the secret of making glass,&nbsp;and kept it a secret were dismantled and the rest of the world found &nbsp;out how to make glass.&nbsp; The Venetians made good use of their knowledge and made good use of &nbsp;this knowledge and they were artistic as well. They were the first &nbsp;people who made glass bottles and artistic things from glass.&nbsp;&nbsp;</p>
<blockquote>A major milestone in the history of glass occurred with the invention of lead crystal glass by George Ravenscroft.&nbsp;</blockquote>

<p><a href="https://imgoat.com/uploads/7d1e990583/147595.jpg">image source&nbsp;</a></p>
<p>What this meant was that the glass was softer and of better quality. &nbsp;</p>
<p>Because of this invention it made life easier for people to make lenses &nbsp;and this is where the original came from.&nbsp;&nbsp;He could make optical lenses and this made it possible to start making telescopes and microscopes were invented. &nbsp;</p>

<p><a href="https://www.thoughtco.com/hans-lippershey-3072382"><em><strong>Hans Lippershey</strong></em></a> &nbsp;Is said to have made the first telescope that became widely known all &nbsp;over the world. He was from Holland. When all these clever people like &nbsp;Sir Isaac Newton and others that started using mirrors in their &nbsp;telescope to make things a lot bigger than they were, it was time for &nbsp;the binoculars to appear.&nbsp;&nbsp;</p>
<blockquote>Credit for the first real binocular telescope goes to J. P. &nbsp;Lemiere who devised one in 1825. The modern prism binocular began with &nbsp;Ignazio Porro's 1854 Italian patent for a prism erecting system. &nbsp;</blockquote>
<p><strong>Binoculars are just to telescopes, one for each eye that are &nbsp;put together and made smaller so that you can use them with your hands &nbsp;and move around freely .</strong> Here is a video on how they make binoculars today.&nbsp; &nbsp;</p>

<p>If it were not for these very smart people we would not have been &nbsp;able to see the stars and there would be no people who could go bird &nbsp;watching. &nbsp;&nbsp;</p>
<p>Thank you for reading my post.&nbsp;Have a wonderful day from me.&nbsp;</p>
