Isambard is named after Isambard Kingdom Brunel , one of the most famous engineers of the nineteenth century. In England, he is still widely regarded as a technical genius. Brunel did not think in terms of limitations. He constantly pushed the boundaries of what was possible. Together with his father, he built the first tunnel under the Thames, a technical marvel at the time. In addition, he designed the famous suspension bridge at Bristol...]]></description><link>https://www.xar-publishing.com/post/isambard-kingdom-brunel-1</link><guid isPermaLink="false">6aabb325806f253b748787f9</guid><pubDate>Thu, 17 Sep 2026 09:30:24 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/75b2e5_260da7fa9cd14f96bc33bcfe9aed2c47~mv2.png/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>simon </dc:creator></item><item><title><![CDATA[What is spacetime? Window into Spacetime]]></title><description><![CDATA[Space and time seem like two completely different things. Space is everything around us: left and right, front and back, above and below. Time is what a clock measures. However, Albert Einstein discovered that space and time do not exist separately. Together they form a single whole: spacetime . That sounds complicated, but actually, we notice something of it every day. When you look at the sun, you do not see it as it is at that moment.

The four rocky planets: Mercury, Venus, Mars, and Pluto, are particularly inhospitable to humans, and the remaining gas planets are impossible even to land on. The planets and their moons in our solar system are unsuitable for habitation. So other stars seem attractive, but that is where the problem begins.
