Salah Obaya

Salah Obaya 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 Salah Obaya rather than just read about it. In short: Salah Sabry A. Obayya is an Egyptian Professor of Photonics and the director of the Center for Photonics and Smart Materials at the Zewail City of Science and Technology.

Key takeaways

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

Reference excerpt

Salah Sabry A. Obayya is an Egyptian Professor of Photonics and the director of the Center for Photonics and Smart Materials at the Zewail City of Science and Technology. He is a member of African Academy of Sciences, Optical Society of America, the Institute of Electrical and Electronics Engineers (IEEE), and Society of Photographic Instrumentation Engineers

Education Prof Salah obtained his B. SC and M. SC in electronics and communications engineering from Mansoura University in 1991 and 1994. He received his doctorate degree in 1999 under the joint supervision of City University London and Mansoura University, Egypt.

Career In 2012, Prof Salah joined Zewail City of Science and Technology and he is currently a professor and director of the Center for Photonics and Smart Materials. However, prior to his commitment in the institution, he had taught in Brunel University, University of Leeds, and University of South Wales where was made the Founding Director of Photonics and Broadband Communications (PBC) Research Center.

Fellowship and membership He is a member of Egyptian Society of Optical Science and Applications (ESOSA), the Institute of Engineering and Technology, the Institute of Physics, the Higher Education Academy, and Institute of Electrical and Electronics Engineers, and Society, Wales Institute of Mathematical and Computational Sciences, Optical Society of America (OSA), International Society for Optical Engineering (SPIE) and Member of Applied Computational Electromagnetics Society (ACES).

Award In 2017, he won Khalifa Award for Distinguished Arab Professor in Scientific Research. In 2019, he won the First Class Order of Sciences and Arts and the State Appreciation Award in Engineering Sciences. In 2021 he won the African Union Kwame Nakroma Awards for Academic Excellence.

Worked examples

Example 1 — a first encounter with Salah Obaya

Start with the simplest possible case. Write down what Salah Obaya 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 Salah Obaya 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 Salah Obaya 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 Salah Obaya

In research: Salah Obaya 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 Salah Obaya 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: Salah Obaya is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Egyptian engineers, Academics of Brunel University London, Academics of the University of Leeds, so understanding it makes those chapters shorter.
In everyday life: Look for Salah Obaya 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.
