Alright, future engineers!
**Conservation of Energy:** Total mechanical energy (KE + PE) in an isolated system stays constant.
Ex: `KE_i + PE_i = KE_f + PE_f`.
Pro-Tip: Always define your system & check for non-conservative forces (like friction) first!

Mediaite: Trump admin deletes cooling advice after right goes scorched on Mamdani for same info. “The U.S. Department of Energy apparently deleted its longstanding guidance that homeowners keep their air conditioning set to 78 degrees, after critics slammed New York City Mayor Zohran Mamdani (D) for giving the exact same advice during the current heat wave.”

What are your tips for using excess energy/saving energy?
For instance, it's hot here right now so if I have to use the electric range to cook, I put a pot of water on after the cooking is done but the range is still hot so the water can be heated up to use in tea or to store in a thermos for later. 🔅
The more it heats the water, the less it's heating the air in the room, I figure.

Noether’s Theorem: Symmetry→Conservation Law.
Symmetries of the action imply conserved quantities per Noether's theorem.
A path q(t) is shifted by δq = φ but smoothed in transition layers τ wide at t0 and t1, where Δq̇ ≈ φ/τ. Action changes there approximate ΔS ≈ (∂L/∂q̇) Δq̇ τ ≈ −(∂L/∂q̇ φ)(t1) and ≈ +(∂L/∂q̇ φ)(t0).
Symmetry sets total ΔS = 0, hence (∂L/∂q̇ φ) is conserved from t0 to t1.Momentum conservation's derivation from space translation symmetry and energy conservation from time translation symmetry in mechanics and physics is done by it.

Alright, future engineers!
**Conservation of Mechanical Energy (CME):** Total KE + PE stays constant if only conservative forces act.
Ex: `1/2mv_i^2 + mgh_i = 1/2mv_f^2 + mgh_f`
Pro-Tip: If friction/drag is present, total mechanical energy is *not* conserved (some turns to heat)!

Good Morning #Canada
Under a sprawling Toronto block of condo towers, offices, shops and six levels of underground parking, lies a huge battery. Known as "the well", it's a thermal battery full of water that provides heating and cooling to surrounding buildings. It's part of the Toronto district energy system that uses Lake Ontario to heat and cool over 100 buildings in the downtown area.#CanadaIsAwesome #EnergyConservation

Reading the dissertation was fascinating because it reveals a side of #Helmholtz that is rarely discussed today. Long before his work on #EnergyConservation, #electrodynamics, and #WavePhysics, he was already deeply engaged with #anatomical and #biological questions.
It also shows that some core ideas about the comparative structure of nervous systems were already being articulated in the early 19th century.

This is good advice received from a local retrofit organisation. I'm always amazed by how many people don't appear to understand this simple fact.
MONTHLY TOP TIP
Did you know how much of a difference closing curtains and blinds can make ?
In summer leaving window coverings closed can reduce the heat input to prevent overheating and in the winter closing them before dark can keep heat from escaping and keep your home feeling cosy. -

I just wrote a blogpost about the system that I've designed to optimise our power consumption so that we can do everything with a 25 A main fuse.
There are an increasing number of networked devices switching things on and off at the best time to consume the cheapest and most abundant electricity.
