Hulda Crooks

Hulda Crooks is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hulda Crooks rather than just read about it. In short: Hulda Hoehn Crooks (May 19, 1896 – November 23, 1997) was an American mountaineer, dietitian and vegetarianism activist. Affectionately known as "Grandma Whitney" she successfully scaled 14,505-foot (4,421 m) Mount Whitney 23 times between the ages of 65 and 91.

Key takeaways

  • Hulda Crooks belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hulda Crooks to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hulda Crooks from memory before moving on to harder problems.

Reference excerpt

Hulda Hoehn Crooks (May 19, 1896 – November 23, 1997) was an American mountaineer, dietitian and vegetarianism activist. Affectionately known as "Grandma Whitney" she successfully scaled 14,505-foot (4,421 m) Mount Whitney 23 times between the ages of 65 and 91. She had climbed 97 other peaks during this period. In 1990, an Act of Congress renamed Day Needle, one of the peaks in the Whitney area, to Crooks Peak in her honor.

Biography Hulda Hoehn was born in Saskatchewan, Canada, one of 18 children of a farming couple. She left the farm just before she turned eighteen and enrolled at Pacific Union College north of San Francisco and later at Loma Linda University. There she met and married Dr Samuel Crooks. She took up climbing in 1950, after the death of her husband, who had encouraged her to start after she suffered a bout of pneumonia. On July 24, 1987, at the age of 91, she became the oldest woman to complete the ascent of Mount Fuji in Japan. Crooks was sponsored by Dentsu and a photograph was taken of her at the top of the mountain. She hiked the entire 212 mile John Muir Trail in the high Sierras, completing the hike in segments over five years. Hulda Crooks was a long-time resident of Loma Linda, California, and a Seventh-day Adventist. She often spent time with children in the community, encouraging them to appreciate nature and stay active. In 1991 Loma Linda dedicated a park at the base of the south hills as Hulda Crooks Park.

Early to bed and early to rise. Out jogging about 5:30am. Jog a mile and walk it back briskly. It takes me 12 minutes to jog the mile and 15 minutes to walk it. Do some upper trunk exercises, work in the yard, and walk to the market, and work According to Congressman Jerry Lewis (R California), one of her hiking companions,

No mountain was ever too high for this gentle giant. With a twinkle in her eye, and purpose in her step, 'Grandma Whitney' showed the world that mental, physical and spiritual health is attainable at any age. Crooks died in 1997, aged 101.

Vegetarianism Crooks became a lacto-ovo vegetarian at age 18 which she adhered to for the rest of her life. Her interest in healthy eating resulted in her studying dietetics and graduating from Loma Linda University in 1927. Crooks worked as a medical researcher for Mervyn Hardinge, Dean of the Loma Linda University School of Public Health. She conducted scientific research on vegetarian diets and during 1963–1964 authored several papers on vegetarianism with Hardinge for the Journal of the American Dietetic Association. In 1988 and 1989, Loma Linda University sponsored the "Annual Hulda Crooks Gala" to benefit medical students and established the Hulda Crooks Scholarship.

Worked examples

Example 1 — a first encounter with Hulda Crooks

Start with the simplest possible case. Write down what Hulda Crooks claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hulda Crooks before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hulda Crooks ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hulda Crooks

In research
Hulda Crooks appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hulda Crooks in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hulda Crooks is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1896 births, 1997 deaths, 20th-century American sportswomen, so understanding it makes those chapters shorter.
In everyday life
Look for Hulda Crooks outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
