2024年诺贝尔物理学家得主、人工智能专家 Geoffrey E. Hinton，一家几代人都是科学家，这之前很多人说过就不复述了，参见附图。
值得一提的是他的姑姑Joan Hinton，中文名寒春，曾经参与曼哈顿计划，1948年后来到中国，为中国农业机械化贡献力量（但并未参与中国的核武器研制计划），可以说是中国人民的老朋友，也是首位拿到中国绿卡的外国人。

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.
