My Flashcards

Definition

Meaning

A large reflecting telescope named after its inventor, astronomer George Ellery Hale.

Specifically refers to the historical 200-inch (5.1 m) optical telescope at Palomar Observatory in California, completed in 1949, which was the world's largest for decades. More broadly, can refer to the series of telescopes Hale pioneered (like the 100-inch Hooker).

Linguistics

Semantic Notes

A proper noun used as a common noun. It denotes a specific class of large, groundbreaking astronomical instruments from the mid-20th century. Implies historical significance and pioneering engineering.

Dialectal Variation

British vs American Usage

Differences

No significant difference in meaning. The telescope is a US artifact, so references are more frequent in American texts.

Connotations

Both varieties associate it with astronomical discovery and historical scientific achievement.

Frequency

Virtually exclusive to astronomical/ historical contexts. Slightly higher frequency in American English due to the telescope's location.

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating 'Hale' (a name) as a descriptive word like 'крепкий' (sturdy). It is a surname.
  • Do not omit the name 'Hale' when referring to this specific telescope.

Common Mistakes

  • Writing 'Hail Telescope'.
  • Using it as a generic term for any large telescope.
  • Incorrect capitalisation: 'hale telescope' instead of 'Hale Telescope'.

FAQ

Frequently Asked Questions

It was named after the American astronomer George Ellery Hale, who was instrumental in its design and fundraising.

Yes, although it is no longer among the world's largest, it is still an active research instrument used for various astronomical programs.

It refers to the diameter of the telescope's primary mirror, which is 200 inches (about 5.1 meters). The size of the mirror determines its light-gathering power.

Primarily it refers to the 200-inch Palomar telescope. However, it is sometimes used informally to include other telescopes Hale championed, like the 100-inch Hooker telescope at Mount Wilson.
