I have installed Ubuntu with dualboot alongside Windows. Everything is working, but I can't connect to wifi. I think Ubuntu didn't download my WiFi adapter's driver. How can I download it? Thanks.

Please check with `lspci` (for internal) or `lsusb` (for USB, external). One of them will identify your hardware. The please edit the question to add that information. Dual boot is immaterial for this case except if you still have Fast Startup enabled in Windows. Disabling it is a MUST for dual-booting.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
