Quirrell was able to shake Harry's hand because at that time, he was not yet possessed by Voldemort. It was only later in the story that Voldemort's spirit took possession of Quirrell's body, allowing him to shake Harry's hand without being harmed. This was a crucial plot point in the story, as it foreshadowed the eventual reveal of Quirrell's true allegiance and the presence of Voldemort. **

I would like to know more about Professor Quirrell's motivations and background. What led him to become involved with dark magic and ultimately serve Voldemort? Additionally, I am curious about his relationship with Voldemort and how he was able to keep his true allegiance hidden from the rest of the wizarding world for so long. Finally, I would like to understand more about the extent of his powers and abilities, as well as any weaknesses or vulnerabilities he may have. **

Yes, in the first Harry Potter book, Professor Quirrell does touch Harry without burning. This is because at that point in the story, Quirrell is not yet possessed by Voldemort, and therefore does not have the same aversion to touching Harry. It is only later in the story, when Quirrell is fully possessed by Voldemort, that he is unable to touch Harry without experiencing pain. **

Before Professor Quirrell, the Defense Against the Dark Arts teacher at Hogwarts was Professor Gilderoy Lockhart. Lockhart was known for his charming personality and his supposed heroic deeds, although it was later revealed that he was a fraud who had been stealing credit for other wizards' accomplishments. He taught at Hogwarts during Harry Potter's second year. **

Information and communication technology is referred to as useful energy because it enables the efficient transmission and processing of information, leading to increased productivity and effectiveness in various tasks. Just like energy is essential for powering machines and devices, ICT provides the necessary tools and resources for communication, data storage, and problem-solving. It plays a crucial role in powering modern economies and societies by facilitating connectivity, innovation, and collaboration. **

In the Harry Potter series, it is established that Harry's scar hurts when he is in close proximity to Voldemort or when Voldemort is experiencing strong emotions. At the time Harry first meets Professor Quirrell in Diagon Alley, Voldemort is still weak and attached to the back of Quirrell's head, and not fully revived. Therefore, it is possible that Harry did not feel his scar hurting at that moment because Voldemort's presence was not strong enough to trigger the pain. Additionally, Harry was not aware of the connection between his scar and Voldemort at that point in the story, so he may not have recognized the significance of the lack of pain. **
