U las de titel van dit boek en vulde spontaan aan met '... denkt een man aan seks'. Waar of niet? Toch zeggen de woorden 'Elke drie seconden' niets over seks, maar wel alles over wiskunde, want drie seconden is een maat en meten hoort thuis bij de koningin der wetenschappen. Deze vaststelling nodigt uit om verder na te denken over seks en wiskunde. Als we wiskunde bepalen als het zoeken naar patronen en structuren en als je aanneemt dat alle menselijke activiteiten patronen vertonen, dan moet ook ons seksuele leven door een wiskundige bril kunnen bekeken worden. Dit boek brengt dergelijke patronen samen. Wat hebben reproducerende konijnen met de gulden snede te maken? Bestaat er een strategie om de ideale partner te vinden? Wat zijn de mathematische grenzen van datingsites? Hoe kan de (ingewikkelde) dynamiek van een relatie beschreven worden? Hoe verspreiden soa's zich? En waarom garandeert meer seks veiliger seks? In Elke drie seconden komt veel wiskunde voor, maar het wordt zo gebracht dat geen voorkennis vereist is. Zo wordt het boek een dubbele ontdekkingsreis: de seks zal na dit boek nooit meer dezelfde zijn en de schoonheid van de wiskunde zal zich blootgegeven hebben, een opwindend vooruitzicht!

Miracle pillow
Size: Standard(Pack of 2)
Best pillow I’ve ever had. I have been using this since December 2024 and it still hasn’t gotten flat. It is amazingly comfortable and solves all my neck issues for a side sleeper. My head never gets hot either. I’ve recommended this to my friends and they’ve had success with it as well.

Really wanted to love these
Size: Queen(Pack of 2)
I really wanted to love these but they gave me a stiff neck. I haven't slept with a pillow since buying these. They are firm except where you lay your head. It just deflates there. I expected it to sink in to match the curve of my neck but it was more than I could handle. My head ended up in a valley between the two ends of the pillow. The price was good, zipper worked fine, it looks as advertised and the pillows are good quality. The cooling part works, its just not what I needed.

best pillow I have ever bought.
Size: Queen(Pack of 2)
most comfortable pillow I have ever bought. It seems very well put together so I believe that it will last a long time. Very happy with the purchase. I do think the weight of the pillow will surprise many people because while it is quite heavy, it is very firm and extremely comfortable. Great value.

I paid for the product and it’s GOOD 👍🏽
Size: Queen(Pack of 2), Size: Queen(Pack of 2)
Honest review to help your decision. These are a bargain at two for one. I paid almost $30 for one at a local retailer and it’s already flattened after 7 months. This product arrives vacuum sealed with the cooling pillow covers separately (separate so you can wash before using). They are loaded with memory foam which I found pleasing. I chose to leave all of the foam in because I’m sure it’ll flatten sometime in the future. I’ve been using these for TWO MONTHS now and they have not flattened. Easy to mold and fluff, soft and they are added support for my back up pillows. I cannot attest to any type of pain relief because I have not experienced that with these personally. I do feel my sleep is better so my tension headaches have lessened. The cooling hex layer is on the cover NOT the actual pillows. I’m sure everyone knows that memory foam gets really hot 🥵 but the cooling covers on these help minimize that. It actually feels cool to the touch like a gel product. I find the quality to be exceptional. All in all, give it a shot.

More soft than firm
Size: Queen(Pack of 2)
Not firm but more soft, would I be returning probably not but if you were already on the fence this is your confirmation that it’s not as described, ( well to my standards at least ) it does feel of good quality but I was looking more a sturdy firm that soft and cushion feeling .
