ALCHEMY - The Physicist

Qwyfyx entered a warm room in which, totally absorbed in his work Albert the Physicist was seated at a large desk.
"Sit down then," said Albert, without looking up.
As there was no other chair in the room, Qwyfyx remained standing and he began to look at some objects on a shelf. He was particularly taken with a gold carriage clock. It was the smallest and finest he had ever seen.

"A gift from my mother," said Albert, looking at Qwyfyx for the first time. "How can I help you, young man?"
Albert sat patiently as Qwyfyx spoke of his adventures. He smiled when he heard about the Philosopher's Stone and, when Qwyfyx had finished, he said with a gleam in his eye; "This disk you speak of, where is it now? Can you show it to me?"

"Well, I, er..." Qwyfyx stumbled for the answer. Only now did he realise that he hadn't seen the disk since he had passed through it. "Um, I seem to have lost it," he said, looking rather distressed.
"Never mind," said Albert reassuringly. "Here, let me give you something to take back to your King."

Perhaps your King will find this a little more interesting.

To Qwyfyx's utter amazement, Albert picked up a magical self-inking quill and wrote a few odd symbols on a sheet of paper.
"For years this was my Philosopher's Stone," said Albert, handing the sheet to Qwyfyx, who looked at it with an expression of utter perplexity.
"Thank you," Qwyfyx said doubtfully. "I only hope my King will understand its meaning," he added, looking wistfully at the clock.
Albert smiled and, standing up, took the clock from the shelf. "I think, perhaps, your King will find this a little more interesting," he said.
"Oh! Thank you!" Qwyfyx beamed. At last he had something of value to take back. Now, even if he didn't find the Philosopher's Stone, he had a present for the King which might help save his neck. "But you said it was a gift from your mother."
"Yes, yes," said Albert. "But if you are taking it back into the past she will be able to give it to me again, won't she?"
"I suppose so," said Qwyfyx confusedly, as he put the clock into his bag.
"Goodbye, Magician," said Albert, as Qwyfyx re-entered the corridor of doors.
