EN： The speaker contrasts 'real science' with 'flashy lab videos' on platforms like TikTok. This reflects a common modern critique of 'edutainment,' where visual spectacle (explosions, color changes) is prioritized over the slow, meticulous, and often repetitive nature of actual scientific inquiry (the 'rigour').
中文： 說話者將「真正的科學」與 TikTok 等平台上的「浮誇實驗室影片」進行對比。這反映了現代對「寓教於樂 (edutainment)」內容的常見批判：這類內容往往優先考慮視覺奇觀（如爆炸、顏色變化），而非實際科學探究中緩慢、細緻且通常具有重複性的本質（即「嚴謹性」）。
EN： The use of a pseudo-cleft sentence structure (The rigour is what...) emphasizes the specific quality (rigour) that performs the action of the verb. It shifts the focus to the subject as the defining factor.

EN： In Western academic culture, especially in the sciences, 'rigour' is one of the highest values. It refers to the strict adherence to logic, evidence, and the scientific method.
