Kommt es unter der Erde zu Vibrationen wenn ein großes Erdbeben folgen wird in den nächsten Minuten? kann man das Vorher voraus sagen?

ByAl13n

Oder ist es schwer zu ermitteln wann und wo der Erdbeben genau eintreffen wird? gibt es den kein Gerät das zu 100% ein Erdbeben erfasst bevor es in wenigen Minuten eintritt und die Menschen das zu spüren kriegen, ein Gerät das 5 min vor dem Erdbeben Alarm schlagen könnte an der Erdoberfläche für die Menschen…

Philodendron einpflanzen?

Byphilodendra

Ich habe hier dieses junge (etwas mitgenommene) Exemplar eines Philodendron Pink Princess und hätte dazu ein paar Fragen. In welches Substrat würdet ihr sie pflanzen? Sie stand davor in (eher minderwertiger) Erde. Und welchen Bedingungen würdet ihr sie aussetzen? Soll ich die große Wurzel intakt lassen oder kürzen, weil sie unten doch sehr vertrocknet ist?…

Kann der Meerrettichbaum auf Stellen wachsen, wo Regenwald zu Sojaplantagen wurden, welche danach unfruchtbaren Boden hinterließen?

Byalex656

Kann er das, und wenn ja, wie ? Weiß, dass er der ‘Baum der Unsterblichkeit’ genannt wird; er hält extreme Dürren aus und braucht keine besonders guten Böden, er wächst auf kargen Böden .

With a simple binoculars (Zoom 8-20x) and a good tripod, you can see “something” but you should at least enjoy a 114/900 mm reflector. I started this a few decades ago *hust*. This is strong enough, even for other objects, and forms the planets sufficiently well for observation. You see – this also needs exercise – the bands on Jupiter, the Saturn rings and the band. Shadow game of the 4 Jupiter Moons. In the case of good “seaing” the Cassinian division of the rings may also be.

Mounting (here three-legged) is important, it should be as stable as possible. Azimut is ok at the beginning, later an equatorial/”German mounting” would be much better, but also more expensive.

Of course there are 130-150mm for ~250€…

I would just like to add that for lens view or even telescopes, correspondingly high-quality opticals with as low as possible color/range distortion as possible and as low as possible color change.

to TE;

With a 100 mm mirror for 100 euros Toys it falls to you in high magnification rates even in the Me you do not seem to be able to respond so well to customers and their needs, because in my eyes the questioner has expressed very well what it wants. scgwer with his as much as possible non-smooth tracking “handish” on his “reisigstativ” with a more massive look than the tripod really offers.

At a few hundred times even a fur on the chair on a swim or laminate quickly brought the whole into problems.

I write from experience!

The “Toys” mirror reflex tube in itself wasn’t even bad with its 150 to 1000, but for 100 Mark, its tripod could be massively desired with Luna and a solid fur on the chair cushion.

Freehand without crank You also don’t have a chance to follow La-Luna in a high magnification factor on such a swabble stand.

At 600-1000 times, said fur on flexible floors…

e.g. something like this: 200/1200 Dobson (opening/ focal length, the magnification results from the selected eyepiece)

To see something like that, you need a telescope.
A binoculars is not enough.
