A university professor Singapore gave a two-hour online lecture but didn't realize he was mute. Professor Wang, who teaches maths, was not aware that throughout his online presentation, the microphone his computer was switched . This meant that none the students attending his online class heard what professor Wang was talking . His university switched his classes online to help reduce the spread COVID-19. His lecture started well but then it froze. The video came back but the mic was and professor Wang did not notice. One his students says it might have been because the professor was using an iPad and not a computer.

Students tried many times to contact professor Wang the lesson but could not get through to him. They waved their arms and even tried calling him his personal phone. A video the moment he understood his mic was off has gone viral the Internet. It has received more than 653,000 views. After realizing what happened, professor Wang appeared shocked and stressed. He said he was upset the thought wasting two hours of his students' time. He has offered to redo the lecture a different time so his students do not miss that class. One his students posted on social media the professor's mishap. She wrote: "I took a class him before and he teaches well. I feel bad him."
