Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | This work deals with the search for signatures of non-Gaussianities in the cosmic microwave background (CMB). Probing Gaussianity in the CMB addresses one of the key questions in modern cosmology because it allows us to discriminate between different models of inflation, and thus concerns a fundamental part of the standard cosmological model. The basic goal here is to adapt complementary methods stemming from the field of complexity science to CMB data analysis. Two key concepts, namely the method of surrogates and estimators for local scaling properties, are applied to CMB data analysis. All results show strong non-Gaussianities and pronounced asymmetries. The consistency of the full sky and cut sky results shows convincingly for the first time that the influence of the Galactic plane is not responsible for these deviations from Gaussianity and isotropy. The findings seriously call into question predictions of isotropic cosmologies based on the widely accepted single field slow roll inflation model.…

Store description
Seit über 30 Jahren handeln wir mit Büchern. Begonnen hat alles als kleiner Fachbuchhandel in Berlin. Heute sind wir spezialisiert auf den An- und Verkauf gebrauchter Bücher. Noch immer liegt unser Fokus dabei auf den Kategorien: Fachbuch und englischsprachige Literatur. Hinzu kommen Bücher aus allen anderen Genres, wie Belletristik, Biografien oder Kinderbücher. Unser oberstes Ziel ist dabei die Weiterverwendung von Dingen und die Schonung von Ressourcen. Neben dem Ankauf von privaten Büchern oder Haushaltsauflösungen kaufen wir bundesweit komplette Bibliotheken und Buchbestände von Institutionen auf, um diese nachhaltig ein weiteres Mal auf den Markt zu bringen. Parallel dazu bietet Buchpark die Möglichkeit, große Mengen einzulagern. Ganze Bibliotheken und umfangreiche Buchbestände werden von uns professionell auf Qualitätsmerkmale hin untersucht und sorgfältig für den Onlinehandel aufbereitet. Wir schenken Büchern ein zweites Leben.…

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to Buchpark, Trebbin, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
