German History: From Kaiserreich to Nazi Collapse
🦅 Kaiserreich and Pre-WWI Context (1890–1918)
- Wilhelmine Militarism: Kaiser Wilhelm II’s obsession with military prestige alienated socialist and democratic factions. He expanded the navy via the 2nd Naval Law (1900), provoking a costly arms race with Britain.
- Authoritarian Constitutional Monarchy: The Chancellor was unelected, answerable only to the Kaiser, not the Reichstag — creating a democratic façade masking autocracy.
- Rapid Industrialisation: By 1914, Germany overtook Britain in steel

1.1 10-mark: Solve T(n)=2T(n/2)+n, T(1)=c
T(n)=2T(n/2)+n
=4T(n/4)+2n
=8T(n/8)+3n
… after i steps: T(n)=2i T(n/2i) + i*n
Stop: n/2i=1 => i=log2 n
T(n)=n*T(1) + n log2 n = n*c + n log2 n
=> T(n)=Θ(n log n)
1.2 Master Theorem (Write As-Is)
T(n)=aT(n/b)+f(n), compare f(n) with nlogb a
- Case 1: f(n)=O(nlogb a – ε) => T(n)=Θ(nlogb a)
- Case 2: f(n)=Θ(nlogb a logk n) => T(n)=Θ(nlogb a logk+1 n)
- Case 3: f(n)=Ω(nlogb a + ε) and a f(n/b) ≤ c f(n) (c<1) => T(n)=Θ(f(n))

What is Psycholinguistics?
Psycholinguistics studies how language is acquired, represented, processed, and used in the human mind/brain. It focuses on language production, comprehension, and acquisition.
Creativity of Human Language
- Human language is infinitely creative.
- Speakers can produce and understand novel sentences they have never heard before.
- This is possible because language uses rules plus a finite vocabulary results in infinite sentences.
Language vs. Speech vs. Thought vs. Communication

Understanding the Central Limit Theorem (CLT)
The Central Limit Theorem (CLT) is one of the most important principles in statistics. It states that when we take many random samples from any population—regardless of the population’s original distribution—the distribution of the sample means will approach a normal (bell-shaped) distribution as the sample size becomes large enough (usually n ≥ 30).
This phenomenon occurs even if the population itself

Insurance is essentially a collective safeguard against the financial impact of life’s “what-ifs.” It is a contract that acts as a buffer between an individual and potential financial ruin.
The Core Components of Insurance
Here is a breakdown of the concept, nature, functions, and importance of insurance.
1. Concept of Insurance
Insurance is a legal agreement between two parties: the Insurer (the company) and the Insured (the individual or business).
The Agreement and Risk Transfer
