Hazem Hosny

Hazem Hosny 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 Hazem Hosny rather than just read about it. In short: Hazem Hosny (Arabic: حازم حسني); also spelled Hazem Hosni; (1951 – 4 February 2024) was an Egyptian political scientist. He was Professor of Political Science at Cairo University.

Key takeaways

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

Reference excerpt

Hazem Hosny (Arabic: حازم حسني); also spelled Hazem Hosni; (1951 – 4 February 2024) was an Egyptian political scientist. He was Professor of Political Science at Cairo University.

Background Hazem Hosny was born in Cairo, Egypt in 1951. He died on 4 February 2024, at the age of 73.

Criticism of Sisi Hosny criticised the policies of Abdel Fatah al-Sisi with Mahmoud Refaat. In January 2018 he supported Sami Anan's bid to contest Sisi in the 2018 Egyptian presidential election.

Arrest Hosny was arrested without a warrant and held incommunicado in late September 2019 during the 2019 Egyptian protests. His legal defence team called for him to be released immediately. Hosny had earlier described Mohamed Ali, who earlier in September had published a video accusing Sisi of corruption and calling for street protests, as playing a "positive role" and described the new protest movement as having the potential to affect the "international formula that largely determines Sisi's continued rule". Hosny argued in favour of "[stripping] Sisi of his dictatorial control of the Egyptian state". Egyptian authorities released Hosny on 23 February 2021, after he spent about a year and a half in pre-trial detention, under the condition that he stay at home as part of his conditional release.

Worked examples

Example 1 — a first encounter with Hazem Hosny

Start with the simplest possible case. Write down what Hazem Hosny 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 Hazem Hosny 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 Hazem Hosny 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 Hazem Hosny

In research: Hazem Hosny 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 Hazem Hosny 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: Hazem Hosny is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, 2024 deaths, Academic staff of Cairo University, so understanding it makes those chapters shorter.
In everyday life: Look for Hazem Hosny 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.
