Q: BBC Online, formerly known as BBCi, is the BBC's online service. It is a large network of websites including such high-profile sites as BBC News and Sport, the on-demand video and radio services co-branded BBC iPlayer, the children's sites CBBC and CBeebies, and learning services such as Bitesize. The BBC has had an online presence supporting its TV and radio programmes and web-only initiatives since 1994 but did not launch officially until December 1997, following government approval to fund it by TV licence fee revenue as a service in its own right. Throughout its short history, the online plans of the BBC have been subject to harassment from its commercial rivals, which has resulted in various public consultations and government reviews to investigate their claims that its large presence and public funding distorts the UK market.

The website has gone through several branding changes since it was launched. Originally named BBC Online, it was then rebranded as BBCi (which itself was the brand name for interactive TV services) before being named bbc.co.uk. It was then renamed BBC Online again in 2008, however the service uses the branding "BBC". The web-based service of the BBC is one of the most visited websites (fifty-fifth most visited according to Alexa in January 2013) and the world's largest news website. As of 2007, it contained over two million pages.

Q: Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena.

The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigor while giving little weight to experiments and observations. For example, while developing special relativity, Albert Einstein was concerned with the Lorentz transformation which left Maxwell's equations invariant, but was apparently uninterested in the MichelsonMorley experiment on Earth's drift through a luminiferous ether. Conversely, Einstein was awarded the Nobel Prize for explaining the photoelectric effect, previously an experimental result lacking a theoretical formulation.

A physical theory is a model of physical events. It is judged by the extent to which its predictions agree with empirical observations. The quality of a physical theory is also judged on its ability to make new predictions which can be verified by new observations. A physical theory differs from a mathematical theorem in that while both are based on some form of axioms, judgment of mathematical applicability is not based on agreement with any experimental results. A physical theory similarly differs from a mathematical theory, in the sense that the word "theory" has a different meaning in mathematical terms. A physical theory involves one or more relationships between various measurable quantities. Archimedes realized that a ship floats by displacing its mass of water, Pythagoras understood the relation between the length of a vibrating string and the musical tone it produces. Other examples include entropy as a measure of the uncertainty regarding the positions and motions of unseen particles and the quantum mechanical idea that (action and) energy are not continuously variable.

Q: CHAPTER XX

A MINUTE TOO LATE

"Well, this looks like a wild goose chase, Dick."

It was Sam who spoke, from the bow of the motor-boat. For over two hours they had been moving up the Hudson River, slowly, scanning one shore and the other with care. They had noted many boats, but nothing that looked like the schooner for which they were so eagerly searching.

"They had a pretty good start of you," said John Slater, the owner of the motor-boat. "Maybe they are up to Nyack or Haverstraw by this time."

"Well, all we can do is to keep on and watch out," said Tom, with a sigh. His disposition, for fun seemed to have entirely left him.

Another half hour went by, and they came in sight of a number of lumber barges, all heavily loaded. The barges were being towed by a big tug.

"I know the captain of that tug," said John Slater. "We might ask him about the schooner."

"A good idea," answered Dick.

They were soon close to the steam tug and the motor-boat owner waved his hand to the captain of the larger craft, who waved in return.

"I want to find a schooner named the Ellen Rodney!" shouted John Slater. "Did you pass her, Captain Voss?"

"I did," was the answer. "She was opposite Nyack, heading in to shore."

"Opposite Nyack!" exclaimed Dick, "How far is that from here?"

"Not more than two miles," answered John Slater, as he turned his motor-boat up the river again.
