[2501.04219] Framing the Fundamental Theorem of Calculus Through Physics-Based Quantities #ITeachPhysics #ITeachMath #Calculus #Physics

arXiv.orgFraming the Fundamental Theorem of Calculus Through Physics-Based QuantitiesThere is a substantial curricular overlap between calculus and physics, yet introductory physics students often struggle to connect the two. We introduce a quantity-based framing of the Fundamental Theorem of Calculus (FTC) to help unify learning across both disciplines. We propose a consistent approach to teaching definite integrals, including shared vocabulary and symbolism, to help students recognize how concepts like change, rate, and accumulation show up in both calculus and physics. We argue that the typical interpretation of the FTC in calculus, focusing on antiderivatives in closed form, doesn't align well with how physicists use or conceptualize integration. We advocate for an additional focus on Riemann sums and the underlying ideas of change, rate, products, and accumulation, which are fundamental in both fields. This approach can help students build a deeper, more coherent understanding of both mathematics and physics quantity. By aligning learning objectives across the disciplines, we argue that students can develop a stronger understanding of foundational mathematical principles.

Cosmic Canvas Program Guides, creative, hands-on activities that explore observation and model making through art and science.

The free guides are designed for facilitators of all backgrounds. They include science background information, helpful links, and tips for adapting activities – no science expertise needed.

I was on the project team that created these guides, and I think they are really good. You should check them out. Links below ⬇️

Welche Farbe hat die Sonne?

Die Erklärvideos auf dem #YouTube Kanal von Martin Apolin sind wirklich hervorragend gemacht. Und beim letzten Satz im folgenden Video musste ich tatsächlich laut lachen. Denn dieses Argument leuchtet nun wirklich auch kleinen Kindern ein:

Eine gelbe Sonne sieht auf weißem Papier einfach viel besser aus…

Ah, dann habe ich Deine Frage erst jetzt richtig verstanden.

Bei der im Video verwendeten Frequenz 3,4 kHz = 3400 Hz beträgt die Wellenlänge

\lambda = c/f = 340 m/s / 3400 Hz = 0,10 m = 10 cm.

Also müssten der untere und der obere Kopfhörer wahlweise 5 cm, 15 cm oder 25 cm voneinander entfernt sein, damit sich die beiden Schallwellen auslöschen (destruktive Interferenz)…

Eindrucksvolles Experiment zur destruktiven Interferenz gleichlaufender Wellen.

Ein Ohrhörer liegt im Inneren der Küchenrolle auf dem Tisch. Der zweite Ohrhörer wird von oben in die Rolle hinabgelassen. Am manchen Stellen löschen sich die beiden Schallwellen gegenseitig nahezu vollständig aus.

Mr. Spock würde sagen: „Faszinierend…!“
