10 prehistoric marine animals that look like monsters
The modern ocean is full of barracudas and sharks, and Cthulhu may also exist, which is obviously a terrifying place. But these deep-sea creatures discovered in recent times have no close connection to the behemoth monsters that once roamed the prehistoric ocean; for example: giant sea lizards, monster sharks or even "super carnivorous whales". In front of these marine creatures, human beings are much smaller.

The Angel of the North
Do you have a landmark that is always there to welcome you home after a long trip; a welcoming sight that lets you know your journey is almost at an end? This may be a mighty structure, like a bridge, or something less significant, like specific graffiti on a road sign.

Living through Ian. Top Story - October 2022.
My home is on Fort Myers Beach but I rode out the storm at my daughter's place in north Fort Myers. I am devastated, grateful beyond words, distraught, happy, sickened, relieved and overwhelmed. We lost so much and we have so much left. Time stands still, and time rushes by. The rollercoaster of emotions rocks you into sleep and back out. We are out of homes and jobs, but we are ALIVE. Barring a couple of acquaintances, everyone has checked in safe and ALIVE. Hence, the happy part. Many cannot say the same. Thinking of those that were not as lucky is the crippling sadness part. So many lives forever changed. So many lost. Lifetimes of treasures and keepsakes gone forever. For tens of thousands of people, memories are all that remain. For thousands of people, anticipation of happy news and fear of bad news still dominates their every thought. There is a strange mixture of hope and rebirth constantly overshadowed by fear, grief and uncertainty. It makes me feel guilty to feel happy and grateful, knowing how many don't get to feel that way right now.

The origin of the invention of the atomic bomb
Why does the atomic bomb have such high energy? I believe this question can be answered by many friends, it is because the atomic bomb uses heavy nuclear fission, but a uranium-235 nucleus fission called barium-141 and the krypton-92 nucleus will lose a little mass, and this lost mass will be completely converted into energy by mass to energy conversion, and the formula is as follows.
