3D扫描泰坦尼克号残骸揭示沉船最后时刻的英雄牺牲
2022年，深海测绘公司Magellan使用两台遥控潜水器在大西洋海底拍摄了约71.5万张照片，创建了精确的泰坦尼克号数字模型。新发现显示，一组工程师英雄般坚守岗位，保持船只供电直至最后一刻，确保救生艇能在灯光下撤离。
数字模型还揭示了其他细节，如被冰山撞碎的舷窗和船尾打开的阀门，印证了幸存者描述。模拟分析表明，船只仅差毫厘就能避免沉没，但六个舱室的破损注定了悲剧。

Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
