1. The most popular form of communication today is probably the text message. It's quick and easy, and you can do it almost anywhere. Texting has become so pervasive that some people have taken it up as a job, helping others write messages in their own voice, or even just correcting grammar and spelling errors. However, there's still something to be said for the beauty of a handwritten note. The act of writing is a direct channel to your thoughts and feelings; it's personal, and written words convey a sense of permanence that they might not otherwise have. What better way to tell someone you're thinking of them or wishing them well?

2. It's easy to see that technology has revolutionized the way we communicate. From the invention of the first writing systems to today's text messages and video chats, we've figured out ways to talk with each other across great distances and in different languages. But what will our methods of communication be like in 2100? I think that at some point in the future, everyone will be able to speak any language, just by wearing a special headset. This device will have a microphone to pick up sounds and a speaker for your ears. It'll also contain a computer chip that can translate speech into many languages. The wearer would simply say something, then select which language they want it translated into from a list on their phone or some other device. A couple seconds later, they would hear their words repeated back in that language.

3. The invention of the light bulb is one of the most important inventions in history. Without it, we would not have electricity, which would mean no computers or internet. Many people claim that the internet is the most important invention over the past hundred years because it allows us to connect with friends and family all across the world and gives us access to a wealth of information. But without the light bulb, we wouldn’t have a way to power our devices! Plus, in our modern society, the light bulb is responsible for so much more than just providing illumination. It has been used in countless ways to make our lives easier and more fun! For instance, think about how much easier it would be to get dressed in the morning if you didn’t have a way of seeing what clothes you were wearing? Or what about driving at night? I'm sure you're grateful for headlights on cars when you're driving after dark!

4. In a friendly tone: I'd personally have to go with Nikola Tesla, the Serbian-American engineer who invented and developed many things that we use today. In his day, Tesla was known for his work on alternating current (AC) electricity supply systems, which enabled the transportation of electricity over long distances. He also constructed a wireless power distribution system and demonstrated wireless communication over long distances, a feat that was crucial to the development of radio technology. In addition, he pioneered several new fields of physics including X-rays and remote control. If you look at it from a standpoint of impact on society, Tesla's inventions have probably done more for humanity than anything else in history, even surpassing the printing press or any other major technological development. If you ask me, there's no doubt about it: he is the greatest person ever in the history of science.

5. Life on Mars in 100 years time will be like life on Earth today but with a few key differences. The first people to settle on Mars will have been born and raised on Earth, and they’ll still remember the wonders of home. They’ll miss the blue skies, green fields, and colourful flowers. But they’ll soon become accustomed to their new home. Mars will not only be different to Earth in terms of its landscape, but also in terms of its climate. Most parts of the planet are like freezing deserts, but there are three places which could support life: around the north pole (where there is ice), at the equator (where temperatures are reasonable) and in the Valles Marineris (a canyon where humans could live underground). Each human settlement on Mars will need an energy source that doesn’t depend on solar power (because dust storms can block sunlight for weeks). The best solution is fusion power, which has not yet been invented. We need to do more research into fusion technology if we want to colonise Mars.
